Initial commit of pastebin fork

[ewhal]

It's quite big rewrite and indivdual commits are not available since its so big. Introducing features like,

• Support for multiple database backends and configurations like dbname/tablename/ports/adresses/etc.
• Support for dynamically adding languages and lexers from pygments, autodetection of language is also supported.
• Support for changing styles (and languages) on the fly, also row-highlightning and rownumbers.
• Support for showing information about when paste expires.
• Support for goo.gl-shortener.
• Extreme debugging =)
• Probably added a few bugs in there as well =)
