Changes to all parts of the project:

• Minor size optimizations
• Commented away some ALIGN JUMP_ALIGN directives in the Int13h handler (they are either in init procedures, procedures that are rarely called or are unnecessary due to conditional assembly)
• Fixed what appears to be a typo in EBIOS.inc

Location:
