Changes to allow MSWin32 to PASS

[alabamapaul]

First and foremost, to work on Windows, IO::All must be patched see IO::All Pull Request #81

After patching my IO::All, I still encountered errors on Windows. To correct those errors, I made the following changes:

• In t/12-populate-basic.t, DBICTest could not delete the database unless you disconnected first.
  • Forcing the $schema variable out of scope causes the disconnect, allowing the database to be deleted.
• In t/compile.t, failed on Windows because regex assumed Linux path separator / but on Windows the path separator is .
  • Using File::Spec and File::Basename makes tests OS independent.

Hey @alabamapaul sorry for the delay, I read this a week ago and think it's awesome, just had not had a minute.
I'll review the changes this week and try to get a release out.
Thanks!
