removed submodule uglifyjs - i don't think it improves performance that much

and also the whole trust of zerobin rests in the JS code, so some people
might feel safer if the can read a servers JS files.

+For Administrators
+------------------
+
+In the index.php in the main folder you can define a different PATH. This is 
+useful if you want to secure your installation and want to move the 
+configuration, data files, templates and PHP libraries (directories cfg, lib 
+and tpl) outside of your document root. This new location must still be 
+accessible to your webserver / PHP process.
+
+> ### PATH Example ###
+> Your zerobin installation lives in a subfolder called "paste" inside of your 
+> document root. The URL looks like this:
+> http://example.com/paste/
+> The ZeroBin folder on your webserver is really:
+> /home/example.com/htdocs/paste
+> 
+> When setting the path like this:
+> define('PATH', '../../secret/zerobin/');
+> ZeroBin will look for your includes here:
+> /home/example.com/secret/zerobin
+
+In the file "cfg/conf.ini" you can configure ZeroBin. The config file is 
+divided into multiple sections, which are enclosed in square brackets. In the 
+"[main]" section you can enable or disable the discussion feature, set the 
+limit of stored pastes and comments in bytes. The "[traffic]" section lets you 
+set a time limit in seconds. Users may not post more often the this limit to 
+your ZeroBin.
+
+Finally the "[model]" and "[model_options]" sections let you configure your 
+favourite way of storing the pastes and discussions on your server. 
+"zerobin_data" is the default model, which stores everything in files in the 
+data folder. This is the recommended setup for low traffic sites. Under high 
+load, in distributed setups or if you are not allowed to store files locally, 
+you might want to switch to the "zerobin_db" model. This lets you store your 
+data in a database. Basically all databases, that are supported by PDO (PHP 
+data objects) may be used. Automatic table creation is provided for pdo_ibm, 
+pdo_informix, pdo_mssql, pdo_mysql, pdo_oci, pdo_pgsql and pdo_sqlite. You may 
+want to provide a table prefix, if you have to share the zerobin database with 
+another application. The table prefix option is called "tbl".
+
+> ### Note ###
+> The "zerobin_db" model has only been tested with sqlite and MySQL, although
+> it would not be recommended to use sqlite in a production environment. If you
+> gain any experience running ZeroBin on other RDBMS, let us know.
+
+For reference or if you want to create the table schema for yourself:
+
+    CREATE TABLE prefix_paste (
+        dataid CHAR(16),
+        data TEXT,
+        postdate INT,
+        expiredate INT,
+        opendiscussion INT,
+        burnafterreading INT
+    );
+    
+    CREATE TABLE prefix_comment (
+        dataid CHAR(16),
+        pasteid CHAR(16),
+        parentid CHAR(16),
+        data TEXT,
+        nickname VARCHAR(255),
+        vizhash TEXT,
+        postdate INT
+    );
+
+For Developers 
+--------------
+If you want to create your own data models, you might want to know how the arrays, that you have to store, look like:
+
+    public function create($pasteid, $paste)
+    {
+        $pasteid = substr(hash('md5', $paste['data']), 0, 16);
+        
+        $paste['data']                      // text
+        $paste['meta']['postdate']          // int UNIX timestamp
+        $paste['meta']['expire_date']       // int UNIX timestamp
+        $paste['meta']['opendiscussion']    // true (if false it is unset)
+        $paste['meta']['burnafterreading']  // true (if false it is unset; if true, then opendiscussion is unset)
+    }
+
+    public function createComment($pasteid, $parentid, $commentid, $comment)
+    {
+        $pasteid  // the id of the paste this comment belongs to
+        $parentid // the id of the parent of this comment, may be the paste id itself
+        $commentid = substr(hash('md5', $paste['data']), 0, 16);
+        
+        $paste['data']                      // text
+        $paste['meta']['nickname']          // text or null (if anonymous)
+        $paste['meta']['vizhash']           // text or null (if anonymous)
+        $paste['meta']['postdate']          // int UNIX timestamp
+    }
+
