Fixed bug in new module installation routine. Added language string "Upgraded successfully".
Implemented Installation of modules on top of an older version. This is done via checking $module_version. Instead of install.php, upgrade.php is then called if it exists in the module package. For module developers: $module_version and $new_module_version are accessible in upgrade.php to find out what upgrade steps need to be taken.
Added the Id keyword for all files
All occurrences of "CVS" in the code are replace by ".svn"
Initial import from CVS to Subversion of Website Baker 2.5.2
