Added user shortcut option feature

[Muguntharaj Subramanian]

Dear All,
I have just added new feature as mentioned in issue number 3 - http://code.google.com/p/ekalappai/issues/detail?id=3

Now user can choose their own keyboard shortcut to change from tamil to english keyboards.

I have uploaded a development version (version: Beta2-dev) for ekalappai team to test before releasing to the public.

You can download and test it from here: http://ekalappai.googlecode.com/files/eKalappai-3.0-beta2-dev-installer.exe
