Version 1.8.1 - Notifications and Ban Fix

[h2]Improvements & Fixes[/h2]

Streamlined the Notifications Menu into a toggle on/off, with a Settings gear to pull open its own menu
Fixed a bug in Ranked Pick where selecting Confirm during the Ban Phase would indefinitely stall the game, forcing both sides to Alt+F4 out:
- In theory, this should not have affected anyone's MMR.
- Do note, in case anyone did suffer an MMR loss from this, the most we can do to "fix" anyone affected is to reset your Season 5 Ranked progress entirely. We have no way of adjusting it on a per match basis.
Fixed loading into a checkpoint in the Campaign not preserving your life, gold, etc.
Fixed not being able to load Wasteland Variant or Mission 24 in the Campaign
Fixed Customize Builder/Tower having a white backdrop
Fixed Turbo Lite not working when playing Solo Survival Online
Fixed a bug in Mega Survival where it would not remember your recent map selection when returning to menu
