[dev1135] Strg/Alt Modifiers for Keyboard Configuration

[Efrye]

Currently, almost every key is already used by something, but adding modifiers like ctrl+[key] or alt+[key] would open up a ton of new combinations.

Alt+i or ctrl+i to open the inventory is a no-brainer for example.

This should be rather easy to add and would make the live of keyboard players so much easier. So, are there any plans to implement this anytime soon?
