Update bundle scripts to handle installation directory being moved

[djhoese]

Attempt at fixing #295. At the time of writing this is just the .sh script, but should work.

I started researching .bat file solutions and came across this: https://stackoverflow.com/questions/130116/windows-batch-commands-to-read-first-line-from-text-file. I'm not sure how Windows handles newlines and carriage returns the way @katherinekolman has it writing to the file. Kat do you think you could look in to this and test it on Windows? The idea is that if you run SIFT once, then move the directory to a new directory and run it again, conda-unpack should run and data should load fine.

I updated the .bat script and tested it on Windows, but I'm not sure why the tests are failing like this...

Looks like a new version of pyvirtualdisplay is breaking things for pytest xvfb: The-Compiler/pytest-xvfb#22

Let's give it 24 hours and then see where things stand. We can limit the version of pyvirtualdisplay to <1.0 if we have to.

A new version of pytest-xvfb just came out, I restarted the tests, and now things seem to be passing.
