2020-09-24	- Fixed some more bugs with struct, and union handling.	mrb0nk500

2020-08-30	- Did some more work on SuBAsm's lexer.	mrb0nk500
	- Optimized the memory read, and write functions. - Made the emulator faster, and cleaner in general.
2020-08-17	- Fixed some bugs in the emulator's assembler.	mrb0nk500
	- Simplified the effective address functions. - Made SuBEditor a bit faster. - JSR, and RTS now support using the RS prefix, which is used to specify the return address size, with an RS prefix of 0 being a return address size of 64 bits, rather than 8 bits.
2020-08-08	- Refactored the opcode table, in order to make the	mrb0nk500
	instruction formatting simpler. - Refactored the instruction table of the emulator's assembler, it now has two parts, the addressing mode bits, and the base value. The base value is what's used to generate the actual opcode, with the addressing mode bits telling the assembler what addressing modes this instruction supports. The reason for doing this was to use less space. For comparison, the previous version used 870 bytes for the instruction table, while the new version uses only 222 bytes. The new version is nearly 4 times smaller than the pervious version. - The B register based ALU instructions now use their own addressing mode, and are specified by using 'b' as the operand for those instructions. For example, to add the Accumulator with the B register, you now use "ADC B" instead of "AAB".
2020-08-08	Did a ton of stuff.	mrb0nk500
	- Changed the file structure of the SuB Suite, so that all variable declarations, symbols, and constants are in a single file. - Moved the C library functionss into a separate file, and made them use stack frames. - Added support for using the emulator's assembler for realtime debugging, to enter it, get in to stepping mode by pressing Ctrl+s, press any other key, then press F1, The reason for having to press some other key before pressing F1 is because it only allows entering the assembler when the keyboard is not ready. - Added the ".res" directive to the emulator's assembler, the ".res" directive tells the assembler to reserve however many bytes specified by the operand. - Fixed some bugs in the emulator's assembler.
2020-07-06	- Implemented a new opcode table.	mrb0nk500
	- Added a new preifx called the OF prefix, which adds the contents of a specific register to the current operand. - Added a table generator, which parses opcode table csv files.
2020-06-22	Did some more stuff.	mrb0nk500
	- Fixed some bugs in the emulator's assembler. - Worked on SuBAsm's lexer some more. - Created a new directory for the SuB suite, and moved all of the SuB suite's files in there.
