#14 CSS support

[Pavel Hlavnicka]

This patch modifies current source, so that support CSS
much more then the current main trunk version (where
the css support is actually almost zero).

Apply as patch -p0 < lxr-css.patch in the lxr
directory; make sure, that directory ../lxr doesn't
exist (if you have more then one copy).

Template stylesheet file is templates/lxr.css. The
stylesheet to be used is defined in the configuration
file near the header and footer templates.

The template $stylesheet is supported while the header
template is expanded. See html-head.html for more.

My goal was to fix all places, where markup is
generated from code. 80% of changes affects the link
(<a>) output. I extended the prototype of the 'fileref'
function and Co. The second parameter of those
functions is the style to be used (put into the 'class'
attribute). I fixed all references to those call over
all the code.

The remaining 20% are changes related to the rest of
the generated markup. i used the <span> tag for formating.

Issues:
- templates vs. generated code: some pages are
generated completely (e.g search results, so user have
no chance to change them. To make this situation
better, I ... (see next bullet)
- I removed the <ul> and <li> tags in the ident page
(where references to searched symbol are displayed), so
browsers, such is Lynx, could have problems. As I said
above, the better solution would be the template
support for this page.
- Glimpse searches are not supported yet
- I didn't understand all stuff in the 'markupfile'
function. The highlighted files work well, but I didn't
get, what are the other formats good for
- Perl comments may be formatted incorrectly (just
feeling :)
- I used my favorite colors and non-underlined links,
somebody else may dislike it
- I changed the header template, so tables are used;
however formatting of the menu (modes) is still a bit ugly
- I added as few class specs. into templates as
possible, some work is to be done here

I'm looking forward to hear your comments

The second version of patch introduces ident page redesign.
At this time template is used, configuration holds new item
for ident templates specification (see templates/lxr.conf).

Simple template is included.

This allows better formatting of the ident page.

This patch is a replacement for prior one, so apply it to
head CVS version.
