WYMeditor don't desinstall cleanly

When you desinstall WYMeditor, related data are still existing on database.

I noticed it after correcting the bug : #312806: Error on desinstalling WYMeditor module. In order to test this bug on your installation, you MUST patch your code with the patch file given in this report. If not, desinstallation process exit with a fatal error.

Details

table variable

The three following fields must be removed :

• wymeditor_containers,
• wymeditor_classes,
• allowed_html_nn, where nn is the format number given by Drupal core during module installation.

Futhermore, installing WYMeditor module leads to set the filter_default_format to the WYMeditor format number previously named nn. This variable must be removed too or maybe set to a default value, 1 for example.
I am currently testing a patch in which I removed it : Drupal is then free to make is own cooking !

Another approach is to store filter_default_format in a variable before WYMeditor installation change it. And to restore it back when desinstalling WYMeditor. But this behaviour is not correct because the filter_default_format may changed between WYMEditor installation' and desinstallation'.

table filter_formats

The line related to WYMeditor (whose field name is set to WYMeditor) must be removed.

table filters

The line related to WYMeditor (whose field format is set to the WYMeditor format number previously named nn.) must be removed.
