fixed thumbnail and file link urls in filebrowser due to path change in upload fields in 2.3.3
Altered retrieval of destination path to include other upload field types.
Added enctype multipart form-data in order to send the data correctly
Changed to using preg_replace for finding first instance of workspace in destination path when JIT is enabled... this way, if a folder deeper in the chain has workspace as it's name it wont get replaced as it would with str_replace.
CKEditor lib update to v4.2.1
Partial fix for http://dev.ckeditor.com/ticket/9998
Merge remote-tracking branch 'andrewminton/integration'
