Implement alternative language (Bahasa Indonesia) parser

- Alternative Language (Bahasa Indonesia) parser (and several new
classes) added (19/22 serials OK)

Just finished my exam, so ~ to do list:
- Adding a selection of language instead of 4 tabs
(main-teaser-original-bahasa indonesia)
- Cleaning up several unused codes and changing page mechanism to Light
Novel instead of Teaser/Original page

Additional note (not yet fixed):
Missing chapter of Baka to Test
Missing link to Kokoro Connect (well, this one is a special case because
of title link >> _~_ )
Missing link to Sayonara Piano Sonata (missing reason not yet found)
Introduce generic alternative language
Implement alternative language separately
Merge pull request #49 from freedomofkeima/master
