[SVN] r7228 (Subversion, Xcode)

[Allan Odgaard]

• replace custom IO.select code with TextMate::IO.exhaust

For run_xcode_target.rb this implies replacing PTY.spawn (which was problematic because of the exceptions thrown) with popen3 and thus marking output sent to stderr as such (current CSS colors it red)

Changed:
U   trunk/Bundles/Subversion.tmbundle/Support/svn_commit.rb
U   trunk/Bundles/Xcode.tmbundle/Support/bin/run_xcode_target.rb
U   trunk/Support/lib/scriptmate.rb
