Most math and backend storage was floats anyways, so most of these changes just half the data copied during function calls without reducing precision.

Otherwise MANUAL_CONTROL messages are still sent at the regular 50Hz. This reduces transmission bandwidth from 0.9kbps when the joystick is used continuously to 0.1kbps when it's idle.
To prevent possible issues from the last high-bandwidth message being lost and the system then not responding for .1s, the last messsage is double-transmit which should prevent those issues.

Be more forgiving about component IDs, but warn developers. Do *not* translate developer debug messages (they would show up in the translation tool). Anyone without sufficient command of the english language will have a hard time contributing or debugging this application and we should not entangle the poor translators in this.

This code previously existed, but wasn't always triggered. Now it should be.

Also these messages are now all translated.

This reverts commit ec799d44.

This reverts commit b34dd86e.

This reverts commit 80f4f133.

Also added translation calls for some UI messages.

The existing logic for filtering out MISSION* messages that don't apply to this instance of QGC wasn't clear and exactly correct. This refactoring reorganizes the code to be more clear and makes it explicit when the messages should be ignored by this instance of QGC.
Additionally a few more status messages are translated to be helpful to our non-English speaking devs/users.
