Make a bit of cleanup with language overrides, so the tests work with various project settings.
Reloading mt_settings in TestAutodiscover._post_teardown is a workaround for FALLBACK_LANGUAGES being changed by these tests due to some interplay of reload_override_setting and the custom TestCase-wide setting override.
Fix typo
Merge pull request #149 from aitzol/master

Little typo in docs
Disable timezone support for tests, as the date / time fields' tests use naive datatime objects and fail if it's enabled.
Be prepared to test with various storages or just with the usual FileSystemStorage, but with an overridden location (e.g. when the storage is created in another apps test before MEDIA_ROOT defined for tests gets set).
It would be nice to also find a way to ensure files are cleaned up with non-file-system storages in case test_translated_models_instance fails in the middle.
Added a 'How to contribute' section.
Context manager for temporarily switching fallbacks on or off.
Test and docs for the new fallbacks toggle.
Use the right comment syntax in docs.

Merge pull request #152 from wrwrwr/feature/fallbacks-toggle

Fallbacks toggle
Update docs about fallback toggle.
Simplified exclusion of translation fields in grouped_fieldsets (thanks to Wojtek Ruszczewski for poiting this out).
Added stable/1.5.x Django branch to env (master is 1.6 now) and used latest stable Django versions.
Added top margin for selects in tabular inlines and excluded date and time fields (this requires more care, added FIXME).
Use latest django releases also in tox.
Added Django 1.5 (it's stable now).
Use 1.5 in tox.
Hotfix for #154
