truecrypt 7.1a-1

New release of my Truecrypt fork. Changelog:

* Added an option to allow users to install only the CLI tool.
* Made the Homebrew build process better respect the number of cores
your CPU has available.
* Truecrypt Usage Guide installed into share so users can actually
access it.
* Truecrypt License installed into share so there’s slightly less
chance of me getting my behind handed to me by a court. And no, nobody
has tried yet, but better safe than sorry.

No other changes.

For the curious, as ever you can see the full commit log and release
notes [here](https://github.com/DomT4/truecrypt-homebrew/).
