number of collections detection is unreliable

[treellama]

It's actually fairly possible to load a Marathon 2 shapes file and have ShapeFusion think it has more than 32 collections, resulting in it loading wrong. See attached:

Also, this editor refused to open certain shapes files from certain scenarios. Its error report states that it reads too low number of collections. The current editor version (from this github repository release, not sourceforge repository release) is 0.7, the number of collections in a shapes file shouldn't be a problem.

See example scenario shapes file below.
