Incorrect text editing keybindings on macOS

[alterae]

Description

On macOS, the keybinding to select all text in a text in a text field is ⌘+A. Pressing Control+A should instead move the cursor to the beginning of the line (and likewise Control+E should move it to the end of the line).

However, in SS14, pressing ⌘+A on a mac does nothing, and pressing Control+A selects the entire contents of a text field.

This is both technically incorrect behavior and a real tripping point for muscle memory for players on macOS.

Reproduction

1. Play the game on macOS.
2. Join any server.
3. Type something in the chat.
4. Press ⌘+A. Nothing happens.
5. Press Control+A. The entire message you are typing will be selected.

Screenshots

Not applicable.

Additional context

While the Control+A/E shortcuts would be very useful (for changing the type of a message I am already writing, and for preserving muscle memory) they are not that important.

The lack of ⌘+A functionality, however, is a real issue.
