v6.0 Discord 2.0 Update!

Moved over to Discord.py 2.0 now. No longer need discord-components module.

• Now able to download server log files. Uses discord's special file embed. Will also unzip any .gz files selected before sending.
• New showlog argument for [runt_bot.py](http://runt_bot.py/). Uses watch and tail commands.
• Able to filter chat logs now with keywords. E.g. ?chatlog minecraft is awesome. Searches latest.log for matching user chat lines containing 'minecraft is awesome'. Can still specificy # of lines, e.g. ?chatlog 5 frog.
• Updated how ?players command works. By default, will now just show player names instead of fetching their coordinatess (which takes a long time, esp if u have a lot of players). Now use ?p location or ?pl to show all player's online and their coordinates.
• Updated and added new commands to command_info.csv file for ?help2 command.
• Can customize wait time after booting mc server before invoking status command.
• If using tmux can now specify which pane to use for mc server and bot.
• Fixed ?timeoff command not working, doDayLightCycle was misspelled in the code.
• Fixed getting server IP using RCON, and some other RCON related stuff.
• Fixed no longer import mctools unless use_rcon = True in slime_vars.py file.

And a bunch of other stuff....
Also, pls no looky in my commit history! It is unholy. I do not know how to use git correctly.....:)
