updated db schema: increased size of the field pattern in order to enable support for executing bigger patterns

vaish: commented out code that was preventing pattern stored in the patterns table to be updated/refreshed after pattern file has been modified

vaish: fixed - ensure proper data format for cases when 'modules' tag contains only single 'module' tag (this got broken when syntax for disabling modules changed recently)

#648198 by vaish: wrong form_id used when creating new role; added 'post' array to form_state to take care of modules who depend on it when altering forms

vaish: paterns_sync_form_values() - fixed handling of mulitple select list and mulitple checkboxes when 'delete' or 'overwrite' attributes used

#692918 by vaish, ergonlogic: Pattern edit form - set correct pattern syntax based on file extension

patterns dev release dated 2009-Oct-02 and older releases are compatible with imagecache 6.2 beta9
patterns dev releases newer then 2009-Oct-02 are compatible with imagecache 6.2 beta10

disabled patterns_sync_form_values function for node forms until incompatibilities between the two are resolved

#590380 by andrewlevine, vaish: Decide if sub-pattern needs to be run based on the mode defined within the pattern or selected in UI at the time of form submission

Allow support for other modules to integrate with patterns by supplying a directory with /components or /patterns
