[squeak-dev] Squeaklets on USB flash

Hi,

ProjectLoading saves a copy of all loaded projects in Squeaklets directory
even when the files come from local sources. This is annoying when running
Squeak off a flash memory chip. The attached change set skips this caching
behavior.

This change is rather harsh and will increase loading latency those who
save/load projects off a remote server. I suspect such folks would already
have a proxy caching server. Does anyone have a better idea?
