[LockDown] Cog redoing

[SharkyTheKing]

Thanks to @kablekompany for making a PR -> #41

I'll be using this issue to list and detail changes that I'll be making towards Lockdown.

Current list:

• Account for multiple channel addition/deletion.
• Remove cross-guild lockdown (not needed, impossible to account for situations and not worth the effort. Discord stability has been reliable enough to not need this for servers)
• Account for console logging
• Account for channel notifications.
• Account for both Text and Voice channels being able to be locked
• Account for lockdown messages and unlockdown messages not being able to be sent, return message to author saying where they aren't able to be sent.

Linking to PR. #41

I won't be merging this completely, though I will be taking aspects from this PR to expand on from this current code.

#44 was merged and is published, though I'll continue to work on this and add new features as I can.

Probably going to add in a lockdown's ReadMe in the cog file so I can keep track of everything I need to do.
