Two dimensional Visual mode

[radare]

Current visual mode is a bit chaotic, i think we should have pP and switch between modes, but use another key to switch between sub-modes. this is:

• Hexdump (pxa, pxx, pxC, ...)
• Disassembly ( ... )
• Debugger (different debugger views , with ")
• Zoom (zoom out, entropy bars, sections, pxA, ..)

We use the " key to switch between 1 column or multi column modes. We must define the modes for each panel properly
