- remove extractor.php
 - replace readme to inform people on why we are not generating templates for Drupal HEAD

the extactor is web-enabled, so document it, but warn about the possible security problems associated with this use

 - now has command line options for work modes
 - the new default auto mode autodiscovers Drupal files from the current
   folder and subfolders (finds theme files not found before with the suggested
   command line params)
   This teoretically allows the extractor to easily run on Windows, needs testing.
 - the manual file option is still there, just need to add --files before the file list
 - there is a debug option, which only runs the extract on itself (the auto mode
   excludes the extractor, in case it is in the current folder)
 - there is help for these options

 + previous performance changes also forward ported from the 4-7 branch

http://drupal.org/node/11517. I have done this using some command line magic:

find . -name README -exec cp '{}' '{}.txt' \; -exec cvs remove -f '{}' \; -exec cvs add '{}.txt' \;

I will update all occurences of 'README' to 'README.txt' in the conrtib CVS,
soon. I'll also rename LICENSE, CHANGELOG etc. files as soon as I get around
to it.
