Baraha 10.10.1000 updates

We have made several changes to make Baraha more consistent across all languages. These changes were necessary to ensure better interoperability between languages.

1) Added Tulu, Sinhala, Grantha support in BarahaPad & BarahaIME

2) Updated phonetic keyboard with common scheme for all languages

3) LETTER_VOCALIC_R, LETTER_VOCALIC_RR are supported in all languages as ~ru, ~rU. (Ru, RU are not supported)

4) LETTER_VOCALIC_L, LETTER_VOCALIC_LL are supported in all languages as ~lu, ~lU

5) Special symbols ॐ, avagraha(ऽ), svarita( क॑ ), dheergha svarita( क᳚ ), anudatta( क॒ ) are supported in all languages

6) Tamil letters ந, ன can be typed as 'n' only. ந or ன is produced depending on context. ex: பந்து(pantu), இன்று(inRu)

7) Fixed minor issues in all Baraha programs

8) User can convert .BRH files that were created using old Baraha(v10.10.900 or earlier) to updated phonetic scheme
