Improved Makefile

Started using less' --clean-css flag. This flag minifies output by passing it
through Clean CSS. Also started using lessc's second parameter to output
instead of an io redirector because this may be incompatiable with windows.

Removed yui-compressor from Makefile.
Cleaned up and shortened commands.
Removed Compiled HTML

I also added the server/template/html directory to the .gitignore.
Removed Compiled CSS
Change <article> to <main>

According to the HTML5 spec:
  The HTML <article> Element represents a self-contained composition

  The HTML <main> element represents the main content of  the <body>
  of a document or application sans common elements between pages.
