Merge branch 'master' into Shahin
Null terminated all the strings. Added an index for display buffer and a prepare subroutine
Updated make_test.py so immediate data EAs aren't used in any ADD opcodes but ADDI
The display buffer is now mostly integrated. Just needs to be tested now.
Forgot to call the print display buffer subroutine after adding to display buffer
Display buffer now works for the restart prompt. Needs to be incorporated everywhere else.
Removed display_buffer_test.* since it's unecessary now
Actually, we're going to hold off on using the display buffer for now. It might be easier to do without it.
Mostly finished the 'enter to continue' functionality. Just need to debug this one bit
Finished the prompting for user to hit enter now when printing. Yay
Updated OP_SIZE, small_size, small_mode, small_direction

Updated the error made in Read_OP_SIZE,. Also wrote the filters and
READ_EXT_SIZE, READ_SMALL_MODE, READ_DIRECTION and some specific case.
Fixed bug with printing absolute longs as destinations
Added an ascii banner
Merged Shahin branch with danielle branch
Merge branch 'danielle'
Merged robert branch with master
na na na na naaaaaaaaaaa na naaaaaaaaaa na na na na naaaaaaaaaaaaaaaaaa na naaaaaaaaaaaaaa
Fixed memory overwriting bug
added an SR for invalid OPcodes found. Still need to branch to it where appropriate.
Implemented invalid OPcode SR for all the cases where it should be called.
