Add a memstart symbol to the linkerscript
...
This replaces the old way of appending the memory bitmap to the end of the kernel, which started causing problems with expansion..
I hardcoded the value to 0x1440, which is the start of the first FREE block of memory given to SeaBIOS in QEMU. This should be changed in the future..

Attempts at fixing paging.
...
Have somehow fixed the drawing routines along the way.
I also tried to implement a better keyboard handler, but that's quite a ways away right now.
