Doc comment spelling fixes.
Removed unused imports.
Added --channel argument to CommandQuote.
Added ability to leave off # in --channel arg.

Also, there probably should be a way to check if the channel is one the
bot has been on, or does the SQL handle that?
Removed unneeded comments.
Moved libraries to "lib" folder.

Rather than having them at the root of the project.
Deleted ##UBTesting.ub2log; no longer needed.
Fixed CommandUD

This solves issue #24 and its duplicate, issue #33.
Added CommandWolfram, fixing issue #23.
Made Command.getAccessLevel() default to USER.

Command.getAccessLevel() no longer needs to be overridden if the access
level is Level.USER.
Added CommandPing.

This fixes issue #30.
Alphabetized list of Commands, and formatting fixes

Also registered CommandPing and CommandWolfram, because I forgot to do
that when I added the commands.
Fixed CommandMessageStats

Just had to replace "channel" with "channel.getName()" in a couple
spots.
