Extracted new API styles dependent on API 16 and 17 into values-17.

This involved the typical Android design pattern of a "Base" style in
`values/styles.xml`, then the an empty normal style which uses that Base style
as a `parent` also in `values/styles.xml`, and finally any API specific
styles in another version of the normal style in a `values/styles-v17` folder.

Same was done for android:actionBarStyle moving it into into values-v11.
This time, didn't worry about the base style, because there was not much to be
gained. by doing so.
