keyboard add ability to specify temporary custom layouts

Browse source 
rb core allows you to load custom keyboard layouts

this patch adds the ability to load a keyboard layout in a buffer
the custom layout is temporary and does not overwrite the current layout

use like so:

    unsigned short kbd[64];
    unsigned short *kbd_p = kbd;
    if (!kbd_create_layout("ABCD1234\n", kbd, sizeof(kbd)))
        kbd_p = NULL;

    rb->kbd_input(buf,sizeof(buf), kbd_p);
