Disabled changing scene collections in settings.

Disabled changing, adding , renaming, and removing scene collections in
Settings General while streaming.
Update CrowdIn script to use new folder structure
Allow recording even when SaveToFile is disabled

This changes the semantics of SaveToFile from "disable all file output
when disabled" to "automatically save stream to file when enabled",
which allows the "Start Recording" button to be enabled even when
SaveToFile is disabled.

Having the "Start Recording" button enabled now depends on having a
non-empty SavePath

Disabled changing Scene Collections in Settings:General while streaming.
Change lower limit of video bitrate from 100kbps to 64kbps

If we use high quality audio streaming by mp3 320kbps at NicoNicoLive
streaming service in Japan,
since the total bit rate has been limited to 384kbps, We hope to change
lower limit of video bitrate from 100kbps to 64kbps.
Remove OBS directory from CrowdIn script again, since OBS Studio localization will be in a different CrowdIn project.

Update recording logic to better reflect ConfigFile settings

ConfigFile doesn't distinguish between non-existent keys and keys with
an empty (string) value; therefore we default to treating an empty
SavePath as default save path (and warn the user when setting an empty
SavePath)

Recording is now always enabled (unless previewing)
