[PATCH] gitweb: Refactor project list routines

[Petr Baudis <pasky@xxxxxxx>]

This is a preparatory patch for separation of project list and frontpage
actions; it factors out most logic of git_project_list():

	* git_project_list_all() as a git_project_list_body() wrapper for
	  complete project listing
	* git_project_search_form() for printing the project search form

Also, git_project_list_ctags() is now separated out of
git_project_list_body(), showing tag cloud for given project list.
