Rewrite command word detection

[mattordev]

Currently, the command word detection will trigger a command word based on if it finds a command word ANYWHERE within the supplied voice input. This becomes problematic for stringing together more complex command chains or sentences in general.

For example, if I was to say:
"What's the status of that project?"
With the current system, this would trigger the check system status command because that's the trigger word for that command.
