On windows this will return the documents\video directory, but on
linux/mac it'll just return $HOME for the time being because I don't
know if there really are any other appropriate adequate paths to use.
Perhaps someone else can be willing to fill this in if they wish.
- Move over the last of the original settings dialog code to QT. It was
actually a bit easier to write in the QT version. wxWidgets was
definitely not ideal for that because the pages would fully
create/destroy every time.
- [Win32] Fix os_dlopen so that it only appends .dll if not present
- [MacOS] Fix name dialog text edit widget issue (it would be better if
we could just use the list widget for editing labels, will have to
look in to that in the future)
- Tweak the settings UI a bit more and make 30 FPS default
- Add a macro to convert a QString to a UTF-8 const char * string
- Rename build/plugins to build/obs-plugins
- Remove the last of the wxWidgets code
