Changed command input
Changed command input

-Removed debug trap. Should eventually use this entirely, but right now
 PROMPT_COMMAND is easier.
-Can't enter the same command multiple times. We only record it once.
 Eventually handle this case and create options for it.
-Can now handle hashtags.
-Fixed a bug where it was entering commands over and over for submitting
 empty prompts.
