[Pharo-project] Xtreams's FileDirectory dependence

Xtreams depends on FileDirectory in at least three places, all in the Xtreams-Terminals package. (Three messages on FileUrl, #appending, #reading, #writing; two tests in XTFileReadingWritingTest >> #setUp and #tearDown) Pharo 2.0 has no FileDirectory. So it seems like the easiest (not necessarily simple, nor right) thing to is to break that out into Xtreams-Terminals-Squeak and Xtreams-Terminals-Pharo packages, and similarly for the tests. After that, we'd need to adjust the ConfigurationOfXtreams. I think I forgot to fulfil a promise to submit an updated version of this that loaded FFI correctly (sorry!). Thoughts? Do any Pharo folk load Xtreams? frank
