[PATCH GSoC] gitweb: Add support for enabling 'write' feature

[Pavan Kumar Sunkara <pavan.sss1991@gmail.com>]

Provide $feature{'write'} to enable the 'write'
functionalities for gitweb. While outputting HTML
it checks for gitweb_check_feature('write') and if
it's enabled, proper links will appear along with
the HTML divs.
