[PSDK]

[PSDK]
- Enable the specstrings.h in shlwapi header (since we have it)
- Add missing BIF_SHAREABLE define (which exists in the 2k3 PSDK), even if it's not used at all in our code (and in wine either); I use it in msconfig for a shell browse dialog (because I want it to behave as I expect also on windows).
