Jakub Narebski e88ce8a456 gitweb: Make project description in projects list link to summary view
Make (shortened) project description in the "projects list" view
hyperlink to the "summary" view of the project. Project names are
sometimes short; having project description be hyperling gives larger
are to click. While at it, display full description on mouseover via
'title' attribute to introduced link.

Additionally, fix whitespace usage in modified git_project_list_body
subroutine: tabs are for indent, spaces are for align.
