Chat key is configurable in PoE; non default breaks pasting

[vitaminmoo]

Describe the bug
The key to open chat is configurable - I've got mine bound to space for keyboard reasons
This causes the features of PoeKeyboardHelper.cs that use KeyCode.Return to open the chat interface to fail.

To Reproduce

1. Set chat key to space in PoE settings
2. Cause Poe-Lurker to try to send any message or do any command
3. Nothing happens

Expected behavior

The configured key is available in production_Config.ini in the ACTION_KEYS section as chat as the integer ascii character. It'd be pretty cool to parse it out so the user doesn't have to set it in Poe-Lurker.
