Replace $64BITS with sizeof(void *) == 8

This removes the need of setting `$64BITS` and calling `32bits` or `64bits` as this checks the size of pointers at runtime
Fix typo bug in hexdump command. Thanks to vuquangtrong for spoting it :-)
Merge pull request #8 from Tyilo/patch-2

Replace $64BITS with sizeof(void *) == 8
Bump to version 8.0.4 and add two commands to attach to VMware's kernel gdb stub.
Add ARM info to the README
Fix the author of patch… Not my day!!!
Add parameter option to kernel attach commands to support multiple VM instances.
Add two new commands, asm32 and asm64. I often use gdb to quickly assemble asm snippets and the void ptr change killed this since it depends on being attached to a target.
The new commands allow the old behavior.
fix $eflags invalid cast (because now an internal type) by forcing to int with s/$eflags/(unsigned int)$eflags/

Improve the kernel attach commands to support multiple VMs and kgmacros files.
Change layout of command's help.
Change help of all commands to use the same layout as kgmacros.
Remove duplicate enablesolib commands.
Fix syntax of some commands.
Remove left cast while setting eflags register. Doesn't work in OS X gdb.
Rollback the test for 64 bits due to issues with KDP.
Add thumb test flag for ARM disassembly (trick from iOS hacker's handbook).
Fix the show-opcode-bytes setting.
Add a command to disable context information when doing iOS kernel debugging (KDP is too slow and takes too much time to display this info)
Add commands header and loadcmds to dump mach-o header using otool.
Add patch command.
