Layout.html Bootstrapped

This is a rewrite of the `layout.html` template to work on top of Boostrap.
It also replaces the old stylus theme by new modernized bootstrap theme. The theme is written in `theme.less` and `modernized.less` file. The rest of the .less files are Bootstrap's default less files.
To test it on your machine: compile this file MoinMoin/themes/modernized/static/css/theme.less by lessc `$ lessc theme.less > ../css/ `
So the files to look for are:
`theme.less`
`layout.html`
`modernized.less`
Rest of the less files are from bootstrap source.
Rest of the css files are compiled form of less files by lessc.

#ChangeLog from patch #2
Fixed the alignment of sub menu tabs and item views tabs
Added active visual effect to the current tab view
Fixed horizontal scroll bug
Fixed padding inside sub menu
Increased font size for wiki contents

Now the files to look for are :
`theme.less`
`layout.html`
`modernized.less`
'common.js'
