Swap OC.dialogs.alert()'s parameters, so Error is shown
as its title.

Don't do _too_ much escapeHTML()

Also make long variables more readable by splitting them
up into shorter ones.

Also fix some CSS for Firefox.

A bit bugged though ...

 * escapeHTML(everything)
 * curly braces for if
 * camelcase function_to_call
 * add missing semicolae (?)

Fix #2557 and make the whole code more usable.

Two parameters for OC.dialogs.alert, otherwise one will be "undefined".

Also fixed missing translation.

CSS comments don't work like that.

Especially at user without "" PostgreSQL likes to fail.
