lilypond: unbreak build by adding t1utils to buildInputs

gvfs: add more supported protocols in gnome 3.10. Closes #2880

@lethalman!). Now bring it to gnome 3.10, which currently is the default

pass(word-store): add option to include xclip in PATH

xclip is necessary for pass(word-store) to send passwords to the
clipboard / X-selection, rather than echoing to the terminal.

The option currently defaults to false, because someone may not want the
dependency on X libraries and also pass is really quick to build (it's
just a shell script).
Removed non-free kochi-substitute and added kochi from Debian package.
Moved kochi-mincho and kochi-gothic back into one package.
