Change Windows default cache directory to local
From an issue that called for:
The default jedi cache directory is the roaming folder. In my company, we have restrictions on the file size of the Roaming folder (since I believe these settings are synced across computers). The jedi cache really isn't a fundamental user setting that needs to be synced across devices, so it really should be in the local app data folder. So I propose here that the default windows path use the environment variable %LocalAppData% instead.
