Update jquery.ime from upstream

1. Adding new input methods for languages of Africa
without the need for replacement or key combinations:
* Akan (ak, tw)
* Bambara (bm)
* Dagbani (dag)
* Dinka (din)
* Fula (ff)
* Ga (gaa)
* Wolof (wo)

2. Fixing the combining character in Yoruba Alt method
from combining tone to combining accent, for better
Unicode compliance.

3. Minor fixes in existing layouts with replacements and
key combinations for Akan, Dagbani, Dinka, Fula, and Ga.
