- heap allocator now makes sure virtual memory pages are mapped before using them. this means we no longer have to use page faults to allocate frames, it is done automatically.

- fixed the apic code that caused a page fault. it now writes the correct values at the correct physical address
- improved startup logging including displaying how much RAM is installed.
