Fixup balt.shellMakeDirs

* Prefer just calling makedirs, only use shellMove if that fails
* Some saftey checks to prevent an infinite loop
* A few checks to minimize system calls
better error messages when shellMakeDirs fails

longer exists.

Closes #87
fix Backup Settings so it works when using custom bash.ini

Used to fail to take into account the sInstallersData settings, which would
cause Installers.dat and Converters.dat to not be included in some cases.

Closes #98
Fix Load->All, Load->None, and Load->Bethesda ESMs:

Load->All was activating plugins, but the UI wasn't updating
Load->None was attempting to deactivate plugins not allowed by libloadorder
Load->Bethesda ESMs:
* Was only including the main ESMs, not DLC
* bethDataFiles did not have Dragonborn.esm in the list
* Had issues (case sensitivity?) activating plugins

Closes #91
