Fixed select/qlc scope (default: all); fixed dist eunit test; new rebar

gproc:select/1 now defaults to global+local scope (BW incompatible change)
Type specs have been updated to reflect that {Scope, Type} is a valid first
argument to select/2, first/1, next/2 et al.

The gproc_dist_tests module has been improved, and now works (most of the time,
although it can still time out occasionally).
