fix t() with links per http://api.drupal.org/api/HEAD/function/t;

add rules for <br> and uppercase XHTML;
move includes/tests to tests and move coder_drupal.inc coder_style.inc;

#108849 reported by add1sun - because coder was not properly handling multi-line quotes, had to significantly overhaul the parsing, which should be more accurate and much faster now, and also adds the capability to check html.

Fix #107444 from webchick - only perform regex rules on php, not html - skip characters between ?> <?php

fixed case-insensitive check that was accidentally removed;
started a tests folder and added a couple of style tests

1. camelcase should allow stdClass - http://drupal.org/node/106585
2. allow global variable names from core
3. fix check for extra spaces between the function name and parenthesis
added #not rule to facilitate above

this is actually a major overhaul of the rule warning system -- implementing a
#warning_callback option and moving the t() processing out of the rule.

Look for a space before function names so we have fewer false positives;

fix false warning;
fix misspelled word;

added upgrade50 check for .info file

Update include plug-in formatting;

Add security warning about $REQUEST_URI

Fix drupal callback to use new comment argument

Add a few more Drupal coding styles;
Remove #coder_ignore in preparation for better string handling

fix display of <? ?> in coder_drupal.inc

Add #coder_ignore directive
Remove ?> from include files

Look for trailing ?> (probably unnecessary because CVS strips this from modules)
