The Scene Collection Importer would attempt to set the new filename
using the name property of the scene collection. However, it would
determine an unused filename, and then replace spaces with underscores,
which could cause a name collision. This changes the importer to replace
spaces with underscores first for the base filename, and then determine
an unused filename.
Signal only needs to be connected once, not every keystroke.
Also commit data only when text widget focus is lost to fix cursor
moving to the end of the string after every keystroke.
This replaces the previous Open File dialog for importing collections
with a window for importing many collections at once, based on the remux
window, along with support for importing from OBS Classic, XSplit
Broadcaster and from Streamlabs' fork. This also translates sources
between OSes that Studio supports.
