Added a workaround for an issue which causes JS errors on destroying CKE instances after multi init.
Init CKE only one time (if RichText is enabled).
Improved datepicker to better match the flat design, thanks to Nils Leideck.
Fixed: Find.pm "Can't cd to .." error in DynamicField subdirectories (bug#10587).
Typos.
Removed no longer needed special handling for some ITSM modules.
 Updated SupportBundle email address.
Improved CKEDITOR instance check.
Reimplemented otrs.SetPermissions.pl.
- new option --skip-article-dir
- new option --dry-run to check what will be changed
- removed option --secure as OTRS has been dysfunctional with this option for a while
- removed option --not-root as it defeats the purpose of this script
- removed other unused options
- script runs much faster, only changes permissions if needed
