Version 1.03

- Added labels to field configuration to make it much easier to
understand what the fields do
- Field types have been divided into 'type' and 'mask' for easier
categorization - e.g. bbcodeeditor is now considered 'textarea' with
mask 'bbcode'
- WYSIWYG editor has been changed from CKEditor to something more
lightweight
- Code Editor has been changed from CodeMirror to something more
lightweight yet more feature rich
- Javascript files renamed and unnecessary ones deleted
- '+Options' button when adding/editing fields now only comes up when
the metadatawindow has fields in it
- And more
