/configcommands functions should include more information

[willkroboth]

Currently, the configcommands functions command looks something like this:

Console:
> configcommands functions configcommands Boolean nonStatic !
[INFO]: Aliases: [!, not]
[INFO]: Possible parameters:
  var.!() -> Boolean
  var.not() -> Boolean
> configcommands functions configcommands Boolean nonStatic and
[INFO]: Aliases: [&&, and]
[INFO]: Possible parameters:
  var.&&(Boolean) -> Boolean
  var.and(Boolean) -> Boolean

I want it to look more like this:

Console:
> configcommands functions configcommands Boolean nonStatic !
[INFO]: Class: Boolean
[INFO]: Function: not
[INFO]: Aliases: 
[INFO]:   - !
[INFO]: Description: Returns the logical not of this Boolean
[INFO]: Parameters: none
[INFO]: Returns: The opposite of this Boolean
[INFO]: Examples:
[INFO]:   Boolean.("true").not() -> Boolean.("false")
[INFO]:   Boolean.("false").!() -> Boolean.("true")
> configcommands functions configcommands Boolean nonStatic and
[INFO]: Class: Boolean
[INFO]: Function: and
[INFO]: Aliases:
[INFO]:   - &&
[INFO]: Description: Returns the logical and of this Boolean and another Boolean
[INFO]: Parameters:
[INFO]:   - Boolean other -> the other Boolean
[INFO]: Returns: true if this and the other Boolean are true and false otherwise
[INFO]: Examples:
[INFO]:   Boolean.("true").and(Boolean.("true")) -> Boolean.("true")
[INFO]:   Boolean.("false").and(Boolean.("true")) -> Boolean.("false")
[INFO]:   Boolean.("true").and(Boolean.("false")) -> Boolean.("false")
[INFO]:   Boolean.("false").and(Boolean.("false")) -> Boolean.("false")

The new indentation scheme where every new line has [(time) INFO] before it should be easy with the new IndentedCommandSenderMessenger class, but the help messages and examples and such might require a new Function definition system. The current system isn't great anyways, with a bunch of methods in InternalArgument to format Strings and a bunch of generic VarArgs issues.
