Filetree reader needs to ignore hidden files

[jecisc]

Currently, you cannot load a project in OSX if the sources are on a shared drive or external drive because OSX generates hidden metadata files that filetree tries to load.

I will change that in Pharo and I would like to synchronize the changes with the official Filetree. But I don't know in which branch I should commit that. Any pointers?

Pharo's fix: pharo-project/pharo#2126

[dalehenrich]

gemstone2.4 is the gemstone branch.
pharo* are the pharo branches.
squeak* are the squeak branches.

Unfortunately there is no common branch ... this repo was one of the first github repos and the theory that the master branch would be the common branch never actually worked out --- early on the implementations started diverging in non-compatible ways ... in the past I have cherry-picked a fix when it involved "common code" ...
