Fix console binds incorrectly respecting keyboard layout

While attempting to diagnose #1174 (closed), I discovered another possibly related bug where the console key incorrectly uses the keyboard layout-mapped key when opening and closing the console. This bug can easily be triggered on a non-QWERTY keyboard by binding a button that maps to a different character than QWERTY keyboards do (for example, Z on an AZERTY keyboard). In that case, both the key on the QWERTY layout (bottom-left) and on the AZERTY layout (where W is on a QWERTY keyboard) would toggle the console.

This is fixed by simply ignoring ev_text events when toggling the console, causing it to always use it's QWERTY mapping as intended.
