[Feature Request] Assembler tool small features

[brunovalads]

When working with the Assembler tool, most the time I want to test different things, or different iterations of the same thing I wanna do. I thought some tiny features might help the process:

1. Don't close the Assembler window every time the patch is applied. It's nice to have it opened and with the code editor untouched, to continue testing different iterations of the same code;
2. When applying the patch and the Debugger screen opens, it would be nice to already have the "Start address" used in the Assembler as a execution breakpoint already toggled (type: CPU Memory, break on: execution, address: specific or maybe range with that range the Assembler identified);
3. The possibility to paste in the "Start address" textbox.
