A few of the old level members will also be moved to the new class, now that workaround getters can be implemented.
These currently spit out some deprecation warnings which will be addressed next.
This deals with what seems to be the only hardcoded piece of text in Strife. Also added a translation to the French file and removed a few superfluous line breaks in the English one.
Note that this completely disables the newly added keywords 'play' and 'ui' for unversioned code to allow using them as identifiers as I have found at least one mod that uses a variable named 'play' that would have been rendered broken otherwise.
This also disables many ZScript only keywords for other parsing jobs.
- do not resolve the backdrop texture to a texture ID at load time. This will allow custom menu classes to use this info differently.
- added a new ZSDF userstring property to dialog pages to give mods more means for customization.
- allow overriding the conversation menu class both globally through MAPINFO and per conversation in ZSDF.
