[PATCH] gitweb: Harden and improve $project_filter page title

[Jakub Narebski <jnareb@gmail.com>]

Commit 19d2d23 (gitweb: add project_filter to limit project list
to a subdirectory, 2012-01-30) added also support for displaying
$project_filter, if present, in page title.

Unfortunately it forgot to treat $project_filter as path, and escape
it using esc_path(), like it is done for $filename.

Also, it was not obvious that "$site_name - $project_filter" is about
project filtering: use "$site_name - projects in '$project_filter'".

Though we should probably also esc_path($project), not only
to_utf8($project) in get_page_title() subroutine.

So I am not that sure if it is really necessary, or if I should follow
it by further hardening of get_page_title().

Anyway I have noticed this when I was examining gitweb code for
generating page title, considering adding information about search for
project search.  So this is patch I will be depending textually via
context lines on.
