PR for 2.0.3 release

Notes:
- The branch akbargumbira:develop is identical to AIFDR:develop, so basically it will merge AIFDR:develop to AIFDR:master.
- All tests on jenkins for develop branch are passing

Bug Fixes:
- Fixed north arrow issue on template option (https://github.com/AIFDR/inasafe/issues/855)
- Fixed map_qrc_to_file function. This will allow inasafe package to exclude resources folder for the release. This fix is followed by some adaptations on impact merge tools (used compiled resource instead of resources from file system, used temp_dir for generating temporary html report)
- Fixed template issue (https://github.com/AIFDR/inasafe/pull/867)

Improvement:
- Refactored save scenario tools to a better state

Updates:
- Changed email on metadata
- Screenshots for application help
- Changed subdomain configuration for downloading OSM data (https://github.com/AIFDR/inasafe/issues/868)
