Ability to mass rename selected assets to TRACK00 ... TRACK99

[ItsPepperpot]

As requested by skyweiss: Would be nice to be able to select many objects and rename them all to convert them to slides.

Possible implementation:

• Check if at least 1 item and no more than 100 items selected.
  • If more than 100 selected, warn user (?)
• Iterate through selected with a counter for the current track.
  • If current asset already named TRACKXX, go to next asset. Otherwise...
  • Check if TRACK + Counter# exists already. If it does, increment counter until the asset can be renamed (track not used by another asset)
  • If counter exceeds 99, there are no available track names. No more tracks can be renamed, skip all remaining selected assets.

It looks possible to have tracks with names above 99, e.g. TRACK151 as seen in Rock Slide (TR01) Doesn't appear to work in custom levels though, perhaps a hard-coded thing 🤔
