#6 Problems if installation directory is moved.

[amicitas]

When hystrix is installed (or rather when it is run for the first time) the installation directory is determined and saved.
If the installation directory is moved then hystrix tries to use the saved installation directory and fails to find things.

I need to do one of 2 things:
1. Redetermine the installation directory each time hystrix is run. If I do this I need to be sure that this determination is always done right.
2. Check the installation directiry each time hystrix is run, and if it does not exist/match then try to fix it.
