UI: Create OBS Studio folder for default recording location

[Warchamp7]

Description

This updates the default directory for recordings to be a newly created OBS Studio folder inside the default directory
%UserProfile%/Videos/OBS Studio on Windows
/home/<User>/OBS Studio on Linux (?)
/Users/<User>/Movies/OBS Studio on macOS (?)

Code for Linux and mac will need review and suggestions because I am completely guessing there and it will almost certainly not compile.

Motivation and Context

Better organization for users

How Has This Been Tested?

Tested on Windows.

Ensured the directory is created during initial startup and properly set for new Profiles.

This should be unnecessary as the directory is created on demand when a recording is started. OBS should not create an empty folder in the user's video folder just from being run.

[Warchamp7]

1. It does not create the folder on demand in my testing
   

2. I disagree and believe the folder should be initialized when OBS first runs like any app other storage location

[notr1ch]

This isn't an app storage location though, this is the user's data folders. Well-designed apps should respect a user's folder layout and not create empty files and directories.

[Warchamp7]

Do you have some sort of guidance or documentation from Microsoft about that?

I have multiple applications on my system that have created folders for themselves in the Videos library location

[notr1ch]

It's just good behavior, just because other apps are shitty doesn't mean we should also be shitty. There's plenty of evidence of of users who desire such behavior from their apps.

[PatTheMav]

One's shitty behaviour is another's expected behaviour though. And by that token I'd rather have an application create files in its own managed subdirectory than mess up the root of a data storage location.

I do agree that the directory should be created upon first use though. I don't remember Shadowplay creating directories for recordings or highlights until I actually triggered either.

[Fenrirthviti]

I concur with first use, as a user who does not enjoy all the random empty folders I have no intention of using.

Suggested change

	[moviesDirectory URLByAppendingPathComponent:@"OBS-Studio" isDirectory:YES].path.fileSystemRepresentation;
	[moviesDirectory URLByAppendingPathComponent:@"OBS Studio" isDirectory:YES].path.fileSystemRepresentation;

Shouldn't this just be "OBS Studio"? Spaces are fine to pass as a component to this function, and I'm not aware of any issues with spaces in folder names for OBS.
