[p0psicles]

This PR is here for everyone to review and give his/here approval.
If things are missing, we need to add features or whatever, let me know. Will push against this PR.

If approved i'll merge.

, using the scene_exceptions saved in the cache scene_exceptions table.

Xem season scene mappings are shown through the xem icon, through the img elements title attribute. Sickrage's scene name exceptions are indicated through the sickrage ico file.

We do need to change the sickrage logo to the Medusa logo.

Xem scene exceptions are mapped from the season to sceneseason json.
Season excepions from the sickrage github file are directly mapped to the season number.

Every time I open a show page I get this error.

Either you make sure that 'indexer' exists, or you set a default value for it, like:
getSeasonSceneExceptions(self, indexer_id, indexer=1)
and don't forget the snake_case (get_season_scene_exceptions)!

Why not just?

for season, xem_season in get_xem_numbering_for_show(indexer_id, indexer).items():
            xem_numbering_season[season[0]] = xem_season[0]

.items() for py3 compatibility. Don't need str() and I would avoid it everywhere it's not needed.

@medariox and even better yet, make it a dict comprehension:

xem_numbering_season = {
    season[0]: xem[0] 
    for season, xem in get_xem_numbering_for_show(indexer_id, indexer).items()
}

also exceptionLists should be both snake_case (and keys shouldn't be camel case) and a dict literal e.g.:

exception_lists = {
    'season_exceptions': sickbeard.scene_exceptions.get_all_scene_exceptions(indexer_id),
    'xem_numbering': xem_numbering_season,  # can also use dict comprehension here directly.
}

Items() is slow and memory expensive in python2. Actually i Used items() but changed it after feedback. I need the string there else its passed as int. If someone wants to commit the snakecase, i think it's fine.
