Oriya Supported

Added support for Oriya to Narayam extension. Currently added schemes for Oriya are transliteration and InScript. Subhashish Panigrahihelped to fix the issues in transliteration scheme. I think more issues may come later, as they want more tuning on it. Oriya translator at translatewikican use this schemes to help their contributions. Since its creation to just before Oriya Wikipedia was less active. Shiju Alex is helping to build a community there. After Oriya typing feature active, I hope, more Oriya people will show their interest in the project, as the one major barrier has bee solved.
