Fixed legacy IDE link to work on Firefox.

Tested on FF32/Win7 x64.
devkit: writeConfig w/ optional callback
devkit: Release version 0.1.6.
cli: Configurator >> writeConfigThenDo: extracted
cli: `amber init` runs `amber config`. Fixes #1055.
cli: bump amber-dev dependency to 0.1.6.

Fixes e8725b0e. The wrong package.json was bumped there.
Not reverting, though, as it does not harm, either.
Merge branch 'master' into 0.13-prereleases
cli: Prerelase 0.13.0-2.

Runs `amber config` at the end of `amber init`.
