Stop keyword causes parse errors

[TwitchBronBron]

There are some issues with the stop keyword now, probably introduced in #164.

sub Main()
    'this SHOULD be an error
    stop = 123
    
    'this SHOULD be an error
    stop()

    'this should NOT be an error (but...why would you do this?)
    print stop

    'this should NOT be an error
    stop

    'this should NOT be an error
    if true then stop

    obj = {
        'this should NOT be an error (working correctly right now)
        stop: true
    }
end sub

'this SHOULD be an error
sub Stop()
end sub

'this SHOULD be an error
sub DoSomething(stop as boolean)
    
end sub

Thanks for breaking this down, @TwitchBronBron! 😄

It appears stop is a reserved word and can be used as a keyword but not always. We may also be missing checks for parameter names that collide with reserved words.
