M65: Injecting a basic prg with m65 not working properly about mega65-tools

[Edilbert]

After transferring the program, the pointer "text_top" ($82/$83) must be set to the end of the program text.
It is the same value, like the (eal/eah) = End Address Load = ($ae/$af).
The editor needs this information, if not set to the correct value, the editor will produce strange results or crash.
The fix is, that the transfer program sets this pointer "text_top".

In theory this should be correctly handled by having the X and Y registers loaded with the top address of the LOAD.
But now that we trap the LOAD vector in a more generic manner (see commit for fixing issue #2 ), we probably need to set this directly.

Seems to be fixed by the above.

I've confirmed that this has resolved the issue.
