The old IPA creation process: wrap every dylib files into framework;
this appears to be unnecessary, dylib files can be put outside without
breaking codesigning and validation (only tested with AltStore: it
scans and signs every Mach-O files).
Therefore, IPA builds now allow putting Java Runtimes to
`PojavLauncher.app/jvm`.
Makefile is yet tweaked to adapt this change, will be done later.
Other tweaks
- Disabled autocorrection for text fields in preferences
- The preferences now searches for installed JRE versions instead of
hardcoding them
- Bug fix: "accounts" folder was not created initially, leading to
"username.json does not exist" error
