Vagrantfile is now committed and not changed between configurations. It is
configed by translating the python config file's dict to a YAML file, which
Vagrantfile now loads and uses. This makes it a lot easier for vagrant
users and python programmers to understand, and hopefully makes it easier
to maintain and test with.
Python can easily output dicts as YAML, and a Vagrantfile is a ruby script,
which can easily read YAML. Going this route means that Vagrantfile can
ultimately be committed to git, and the configuration will happen all via
Python dicts output as YAML. That makes it drastically easier to follow
the code, and to make modifications.

Sometimes, buildToolsVersion is a kind of gradle macro call, and other
times it is a variable assignment. This regsub pattern now handles both of
those cases.
This allows the user to set the path to their Android SDK from the command
line. This option is named after the standard env var ANDROID_HOME, as used
in the build.xml generated by `android update project`. --android-home
takes precendence over the ANDROID_HOME env var if it is set.
