Fixes for v1.4.5

Minor fixes and...

Changed default installation location. Comments?

# Reasoning:
1. No more Windows users installing directories like `Downloads` or `Desktop` or worst case: under browser's cache dir
2. No more OS X users install inside .app
3. Easier to find logs
if a user doesn't have write permissions to these directories it should fallback to the older code, as some users can't even get to these folders with some permissions setups on windows domains
