[GNUnet-developers] expand filename diff

[Glenn McGrath]

This diff changes expandFileName to use the wordexp function which handles
environment variable substitution and ~ expansion.

I also made it handle spaces in the filename, i think ive done it the hard
way as i could work out how to use the WRDE_APPEND flag with wordexp.

Im not sure if having spaces in filenames should be supported, or how
portable the wordexp function is.
