Change project name to Wraparound

[eprovst]

Description

Although never intended, Feltix as a name is rather similar to Celtx and might cause confusion... Wraparound (a play on "that's a wrap" a common phrase at the end of the last production day) is neutral, unused by other software.

This also allows us to keep the name of the tool and organisation separate. The tool and file format will become "Wrap".

Sorry about the many issue name changes...

Feltix has been renamed to Wrap and rereleased.
