xml sel fails in linux

[privatezero]

It looks like to take advantage of some of the mmfunctions in linux (at least ubuntu 16.04) that a check will have to be added for system as the command xml sel needs to be xmlstarlet sel. If there are no objections I can make this change!

No objection. On Mac homebrew uses one as the alias of another.

Oh, if it is an alias on Mac, then maybe it would be simpler to just change all instances of xml sel to xmlstarlet sel rather than do a system check to assign the commands?

Also adding as a note to self - there needs to be a system check for fonts too. searchfingerprint's visual reporting will fail silently without it.
