v2.1.0

Version 2.1.0 is the first tagged release, based on feedback from a developer
building a production app with nuxt-native.

Fixed

• Auto-imported helpers no longer override a component's own props of the same
  name (size, placeholder, padding, ...). This only broke release builds.
• <NTabs> works again. It previously used components that NativeScript 9 no
  longer includes.
• <NButton> counts every tap on Android. A quick second tap used to be dropped.
• <NPage> no longer shows an empty toolbar on pages without a title.
• resolveIconSvg() no longer throws when no size is given.
• On Windows, builds no longer fail with 'gradlew.bat' is not recognized when
  the NoDefaultCurrentDirectoryInExePath environment variable is set.

Added

• <NTabs> keeps every tab alive, so switching tabs doesn't rebuild them, and the
  Android back button returns to the first tab.
• useStorage(key, default): a ref saved on the device, restored when the app
  starts.
• Pinia stores can be saved on the device with persist: true or
  persist: { pick, key }.
• Every export in app/composables/, app/utils/ and app/stores/ is
  auto-imported, whatever the file is called. Pinia stores included.
• Names used only in templates are auto-imported and type-check. vue-tsc now
  also checks props of the built-in N* components.
• native.theme in nuxt.config sets the Android window background, status bar
  and accent colours, which removes the white flash between pages in dark apps.
• native.android.minSdk (default 23) and native.android.stopGradleDaemon.
• New projects get a typecheck script with vue-tsc.
• STYLING.md: Android layout pitfalls and how to debug release builds.

Changed

• Android projects now require Android 6.0 (API 23) by default, up from 5.0.
  Current Google Play services and Firebase need it. Set
  native.android.minSdk: 21 to keep the old minimum.
• Gradle's memory limit is now at most 2 GB, and on machines with less than 12 GB
  of RAM the Gradle daemon is stopped after each build.
