Add option to chose working directory that new sessions start in.

[comicsads]

Similar to #4 , but I want the start directory to $HOME for every new session. I went ahead and made the changes for this to work correctly, and haven't yet encountered any issues. You can apply the changes I made by running either command shown here (both will create non-staged changes) git apply startingDirectoriesPatch.txt patch -p1 < startingDirectoriesPatch.txt Here is the patch file startingDirectoriesPatch.txt
