difftool: print list of valid tools with '--tool-help'
Since bc7a96a (mergetool--lib: Refactor tools into separate files,
2011-08-18), it is possible to add a new diff tool by creating a simple
script in the '$(git --exec-path)/mergetools' directory. Updating the
difftool help text is still a manual process, and the documentation can
easily go out of sync.
This commit teaches difftool the '--tool-help' option, which:
- Reads the list of valid tools from 'mergetools/*'
- Determines which of them are actually installed
- Determines which are capable of diffing (i.e. not just a merge tool)
- Prints the resulting list for the user
