Language Selector 1.0.1

Minor fixes.

• Prevented retry timers from infinitely looping and spamming error logs (if an error somehow occurs).
• Added compile error when trying to compile for 1.10 or lower since it does not support OnClientLanguageChanged which is required for CS:GO to work correctly.
• Added in-game checking to the commands.

Language Selector 1.0.0

First release. Yay.
