Small release this time, mostly shipping external contributions.

• Remove the Year 2050 limit in System Settings date picker (rest of system handles 2000-30 Dec. 2099 just fine)
  • HOME menu may crash when setting date to 31 Dec. 2099
• plugin_loader: make plugin reply timeout configurable
• LayeredFS: Call UnMountArchive before Mount (by @R-YaTian, #2200). This fixes crashes when using LayeredFS with HOME Menu.
• Add "Return to Home Menu" option to Rosalina (by @AM7999, #2143)
• Add support for SDK 0.10.2 and 0.12 prototype FIRM (@ZeroSkill1, #2226)
• Further improvements to overall system stability and other minor adjustments have been made to enhance the user experience
