Add support for more branching opcodes

[x87]

Reported by @wmysterio.

Currently the compiler only checks for opcode 004d as a condition terminator. But potentially there are more opcodes:

004c: jump_if_true
0AA1: return_if_false
0AA0: gosub_if_false @label

need a custom datatype in opcode definitions to recognize branching opcodes.

{$CLEO}

0000:
while true
    if
        0AB0:   is_key_pressed 9
    004c: jump_if_true @exit
end

:exit
0A93: terminate_this_custom_script

throws error with Condition Check enabled.

As a workaround the conditions check must be disabled and the if command should be given a number argument:

{$CLEO}

0000:
while true
    if 0 // or 1,2,3...21,22,23...
        0AB0:   is_key_pressed 9
    004c: jump_if_true @exit
end

:exit
0A93: terminate_this_custom_script

A little support could be given to frame_delta_time?

For what can used like this:

0@ += deltaTime * 0.4  // opcode 0079:

The compiler now would also have to check if the keyword (deltatime *) is after the equal sign(=), to know if the XXXX OP should be used.

Yep. See #115

Branching information will be provided by Sanny Builder Library (is_branch attribute). As of now all modes but LCS/VCS have corresponding library definitions. For Stories sannybuilder/library#56 needs to be implemented.

implemented in 3.8.1
