WINDUP-171 TYPE_PROP

According to me :) Definitely it's not 8.

Filemodel is heavily used, so getPathList() can be called a lot of times.
Default size is 8. If the dir length gets to over 16, then it gets doubled (i.e. created 2x size, content copied, and the old garbagge collected) twice for each file.
That should be enough justification. Microoptimization is common in Windup already, e.g. for( : ) vs. for( ; ; ), so... ;-)
