Added support for JPEG images through libjpeg to the bitmap module.
Updated the license and README files accordingly.
Changed the color variable in the bitmap module to unsigned char to simplify some other code.
Exposed a G.getColor() and a BmpObj:getColor() functions to the Lua module.
Modified the G.setColor() function to accept R,G,B parameters.
Merged my latest Musl changes from the Musl source.
These mostly relate to using <> as the not equals operator instead of ~ and the fact that uninitialized variables are now inited to "".
The mu_par_num() function also got renamed to mu_par_int()
