Additions

Now supports running multiple instances of Minecraft at the same time.
Can now be kept open while the game is running, allowing access to things like the help page.
Now backs up launcher_profiles.json (profiles, logins, etc) before migrating settings to new launcher.
Made launch options slightly smaller, so that more of them can fit in the same space.
The button to add a new launch option is now at the top of the list.
"Keep launcher open" and "Show game log" are now separate settings.

Running the launcher from a non-C drive should now work.
- There are still lingering issues with running the launcher at all for some users.
Clicking the .exe again while the game is open now brings back the launcher window instead of doing nothing.

Fixed running modded versions.
Resolution settings should now work properly.
Fixed an issue where opening the game directory would give an error message even when it worked.
Pressing Template:Key in input fields no longer removes the rest of the line.
Pressing Template:Key on the news page no longer messes with the news carousel.
Fixed a crash that would sometimes happen when the game closed.
Selecting input with your mouse and hitting backspace on the keyboard should now properly delete the input.
The version information page no longer selects all text when you click it.

Fixed an issue with the self updater.
- This may mean that users have to redownload the new launcher to get updates.
