David Cook 6d73e951be Bug 11584: Add wysiwyg editor to system preferences dealing with HTML 
This patch adds the ability to use a WYSIWYG editor for system preferences.

The key files that I touch are:

1) admin/systempreferences.pl
2) koha-tmpl/intranet-tmpl/prog/en/modules/admin/preferences.tt
3) koha-tmpl/intranet-tmpl/prog/en/modules/admin/systempreferences.tt

I also add:

4) koha-tmpl/intranet-tmpl/prog/en/includes/wysiwyg-systempreferences.inc

and

5) koha-tmpl/intranet-tmpl/lib/tiny_mce/plugins/advimage

This plugin is part of the TinyMCE distribution. It used to be in Koha, but
then someone removed it. It's useful for preferences like "opacheader" though.

*If you're using anything except IE, this should work super well. If
you're using IE, it'll probably only work for keyboard input and dragging
text within the editor box but not from outside of it. IE has worse
security, so you can probably paste using the context menu paste.

*While I think a WYSIWYG editor can be useful, there might be times
where the content is displayed differently than it is in the editor
because of higher level CSS and Javascript.

ALSO :
this script use an $op to know what to do.
if $op is empty or none of the above values,
- the default screen is build (with all records, or filtered datas).
- the user can clic on add, modify or delete record.
if $op=add_form
- if primkey exists, this is a modification,so we read the $primkey record
- builds the add/modify form
if $op=add_validate
- the user has just send datas, so we create/modify the record
if $op=delete_form
- we show the record having primkey=$primkey and ask for deletion validation form
if $op=delete_confirm
- we delete the record having primkey=$primkey
