Create Gitweb::Parse module in 'gitweb/lib/Gitweb/Parse.pm'
to store the subroutines which related to parsing functions
required for gitweb.
This module depends on Git.pm, Escape.pm, View.pm and Util.pm.
Subroutines moved:
unquote
parse_date
parse_tag
parse_commit_text
parse_commit
parse_commits
parse_difftree_raw_line
parsed_difftree_line
parse_ls_tree_line
parse_from_to_diffinfo
Update 'gitweb/Makefile' to install Gitweb::Parse alongside gitweb.
