Remove debugging information
Added several new commands.
Console commands now access a local scope instead of _G

To avoid conflicts with strict lua in console environments, _L has been introduced. Global variables are saved into this table and attempted to read from it too; access to _G is still possible using _G itself.
Entities are now auto selected.

Jelly.Console+'s select command has been removed, therefore the standard command is used again.
The input history will now ignore empty lines and duplicates
Added clear and ignore whitespace-only lines
