P*tches for B*tches (#483)

* replace /V with global VERIFY ON

* change working dir to script dir
The working dir doesn't necessarily match the script's path, depending on how the script is called. All relative paths and conditional statements using EXIST will fail whenever the working dir is not the script's own location. This fixes that.

* minimal stuff, mostly cosmetic

* prompt to run prefsCleaner under very specific circumstances

* improve -updatebatch option

* add version variable + display new script version on update
