Godot: Double methods for case sensitive functions.

[zaksnet]

Is there a reason that for some classes you have the same method twice like:

int find( String what, int from=0 )
Finds the first occurrence of a substring. Returns the starting position of the substring or -1 if not found. Optionally, the initial search index can be passed.

And:

int findn( String what, int from=0 )
Finds the first occurrence of a substring, ignoring case. Returns the starting position of the substring or -1 if not found. Optionally, the initial search index can be passed.

While you could just have:

int find( String what, int from=0, bool case_sensitive=true )
Finds the first occurrence of a substring. Returns the starting position of the substring or -1 if not found. Optionally, the initial search index and whether the search will be case sensitive can be passed.

Or at least document that find() is case sensitive:

int find( String what, int from=0 )
Finds the first occurrence of a substring. Returns the starting position of the substring or -1 if not found. Optionally, the initial search index can be passed. find() is case sensitive, if you want to ignore case then reference to findn()

Since from what i understand by looking at the code, it could be hard to merge these classes since they are also used internally by the engine.

Probably a candidate for #16863

int find( String what, int from=0, bool case_sensitive=true )

This is already the case for some string methods in C#: https://github.com/godotengine/godot/blob/master/modules/mono/glue/Managed/Files/StringExtensions.cs#L178
