Fix search form generation to not modify $cgi->param(...)'s.
In git_header_html() we used to use $cgi->hidden(-name => "a") etc. to
generate hidden fields; unfortunately to use this form it is required
to modify $cgi->param("a") etc., which makes href(-replay,...) use
wrong replay values. This for example made the "next" link on the
bottom of the page has a=search instead of a=$action, and thus fails to
get you to the next page.
Because in CGI the value of a hidden field is "sticky", there is no
way to modify it short of modifying $cgi->param(...). Therefore it
got replaced by generating <input type="hidden" ...> element [semi]
directly.
Alternate solution would be for href(-replay,...) to use values saved
in global variables, such as $action etc., instead of (re)reading them
from $cgi->param($symbol).

This bug was caused by the fact that git_header_html() modified
parameters in $cgi->param(...) when generating search form, and
href(-replay, ...) uses paramemeters values from $cgi, not saved in
variables (although it could).
This fixes mentioned bug, not only in the case of 'log' view, but in
all cases (although it is possible that this bug doesn't occur for
other pages).
