Merge pull request #44 from MerginMaps/infra

Change wp_mergin to a proper module with functions + fixes

Bug fixes:
1. when pushing to WP mergin project, we correctly report new version if created
   (push call was there twice)
2. avoid ugly warnings from geodiff/sqlite about recovering frames from WAL
   (by closing the sqlite connections when we're done)
