Fluid: fix "trailing whitespace" errors (#100)

Fluid would write trailing whitespace at some points when generating
.cxx and .h files from .fl files.

This was an old issue but became obvious since we removed trailing
whitespace from source and header files recently.

This commit fixes all whitespace errors in files generated from .fl
files in the FLTK repository, i.e. in fluid/, src/, and test/ folders.

I can't guarantee that I found all possible whitespace errors, but
this commit:

Fixes #100
