Made sylph "work" on Debian jessie (ARM).

I _hate_ special cases.
When running on my Nook Color, sylph was segfaulting.

This fix (somehow) changes the segmentation falt into
an error message saying something along the lines of:

   *** free(): invalid next size (fast): 0xNNNNNNN ***

At least it seems to work now...
Added version information.
Switched license.
Removed license.
Added more documentation.
Added debian package build target.
