StreamFin v0.1.2 - removes bogus update popup

Fixes the "0.9.1 is available now! Ready to update?" popup at launch. That was Switchfin's inherited auto-updater checking the upstream project's releases - the version comparison was meaningless for this fork and accepting it failed with an HTTP 404. The in-app updater is now disabled entirely; new builds come from this Releases page.

Also includes everything from v0.1.1: drop a plain-text switch/streamfin-addon.txt containing your addon URL on the SD card and StreamFin imports it at launch - no on-screen-keyboard typing.

Install: copy StreamFin.nro to /switch/ on your SD card.
