This consolidates all of the non-template .gitignore rules into the top level .gitignore, to ignore common things more broadly, with less maintenance needed for the .gitignore files. Does not touch the templates, so that they still produce needed .gitignores as part of flutter create.
* Add framework-side support for system text scale factor.
* Rolling engine to e3404b81a53ba3180c7623a6f2190ebb28518f30

Allows the user to specify the kind of project to create. The default is 'app'. Other choices are 'plugin' (the old '--plugin' behavior), and 'package'.
A Flutter 'package' is a Dart package that depends on Flutter, but does not contain native code.
Fixes#10377.
* Add iOS template
* Android
* Let the engine reset the theme without the activity knowing
* Small tweak
* Replace assets with different vectors
* Let the template hookup have no actual image assets
* Add back placeholder assets with 1px transparent pngs
* Fix drawable xml
* clean up an extraneous line in the storyboard xml
Remove terminating semicolons; they are causing an "code inspection warning" in Android Studio:
```
This inspection reports redundant semicolon (';') token which is not required in Kotlin and may be removed.
```
Going forward, Android support libraries are published on maven (instead of bundling them with the SDK). Many plugins depend on these. To avoid requiring plugin users to add the maven repository to their app this change adds the repository to the template for `flutter create`.
This also bumps the support-annotations dependency to 25.4.0 (which also requires the new maven repository).
IDEA users sometimes want to create multiple Flutter modules
in the same IDEA project. See discussion:
https://github.com/flutter/flutter-intellij/issues/1014
In this case, we will actually have pairs of modules,
one for Flutter and one for Android. Renaming the
android module to make the relationship obvious.
But, don't delete the old file yet to avoid breaking
existing users. We can do that after the next
Flutter plugin release.
