* Improve install code to avoid low-level mistakes.
If a user tries to do a re-install in a Gitea database, they gets a warning and double check.
When Gitea runs, it never create empty app.ini automatically.
Also some small (related) refactoring:
* Refactor db.InitEngine related logic make it more clean (especially for the install code)
* Move some i18n strings out from setting.go to make the setting.go can be easily maintained.
* Show errors in CLI code if an incorrect app.ini is used.
* APP_DATA_PATH is created when installing, and checked when starting (no empty directory is created any more).
* Refactor Logger
Refactor Logger to make a logger interface and make it possible to
wrap loggers for specific purposes.
* Refactor Doctor
Move the gitea doctor functions into its own module.
Use a logger for its messages instead of returning a results string[]
