git-mergetool: add new merge tool TortoiseMerge

TortoiseMerge comes with TortoiseSVN or TortoiseGit for Windows. It can
only be used as a merge tool with an existing base file. It cannot be
used without a base nor as a diff tool.

The documentation only mentions the slash '/' as command line option
prefix, which refused to work, but the parser also accepts the dash '-'
