Revisions for luxor/lib/base.php

Horde_Loader -> Horde_Autoloader

remove singletons and & from references

Fix some escaping, cs, style, etc.

Simplify code to use either GET or mod_rewrite, not PATH_INFO.

- fix array_merge usage
- support mod_rewrite pretty urls
- lots of html cleanup
- code cleanup (avoid array_key_exists, etc.)

Registry::getParam() -> Registry::get().

No more HORDE_LIBS.

Remove includes of Browser.php that are no longer needed.

Config:: and Help:: moved to framework packages.

Browser:: is now a framework package.

[cjh] Various $no_auth and $self_contained_auth flags have been standardized
into an AUTH_HANDLER constant, which if defined signals the application
that it should not check permissions upon calling $registry->pushApp(),
as the calling script will handle that itself, or is a system-level cron
job/script/etc.
[cjh] Add an option to $registry->pushApp() to specify whether or not to check
application permissions.

[cjh] The 'allow_guests' setting, and $registry->allowGuests(), have been
removed in favor of Horde_Perms application permissions.

prevent errors with transparent authentication.

Use horde/lib/core.php in all applications. For now, I've commented
out the HORDE_LIBS-based includes in core.php and we're still using
the old HORDE_BASE . '/lib/' includes everywhere. But the HORDE_LIBS
constant is now available everywhere and core.php is included to
properly set up the base framework.

I also hit a bunch of other base.php things while I was at it:

- always check the results of $registry->pushApp() and display an
error if it fails.

- removed old cache_ssl code which is handled by
Browser::downloadHeaders() now.

- make sure all base.php files check authentication (you may need to
specify allow_guests = true on some applications that were open
beforehand).

- move the auth check up as soon as possible so as not to do
unnecessary work.

- remove libraries and code that aren't used.

- try and organize files consistently.

- probably a few other minor things.

Please test out everything as you can and report problems or syntax
errors; I'm sure I missed a thing or two.

Use the new Util:: class.

[cjh] Improve layout of identifier pages.
[cjh] genxref.php is now solely a command line script and lives
in the scripts/ directory.
[cjh] Make sure to clean out the database before adding new data
so as not to get duplicate entries for identifiers.

- also move Driver and Files base classes into lib/Luxor.php for brevity (they're just stubs),
and other misc. cleanup.

Simplify driver instantiation even more.

No hardcoded params anymore.

- eliminate a few errors checking for ctags
- remove headerbar.inc, not really used.
- add .cgi for perl

[cjh] Add a new API call, Auth::isAuthenticated($realm = null), for
determining whether or not a user is logged in to the current
realm (by default null). Auth::getAuth() is still used to get
the current user, but now you don't need to know the auth realm
to get the current user - just to check authentication.

This commit replaces Auth::getAuth() with Auth::isAuthenticated()
where appropriate. Hopefully I didn't miss anywhere or cause any
problems; let me know if you find anything.

Fix viral typo.

Some more cleanup, Chora look-a-like.

Changed database tables.
Now supports multiply sources (you jave have to edit the bottom of base.php to change at the moment)
Sql backend should support tags but untested.

Allow self contained authentication.

Include Luxor.php and sources.php.

Initial import of Luxor, a PHP port of LXR.
