Description of problem:
For users coming from SCIM it is confusing not to have a default IME set for their language. ibus should default to an IME for the current locale if available and it should be possible to configure a system default IME per language.
Steps to Reproduce:
1. Japanese user starts using ibus and presses Ctrl+Space
ibus shows bubble asking user to configure
ibus-anthy to be activated if installed
