The styles used by the app details showed good padding on either
side of the buttons text. This was because they had a certain amount
of screen space to fill up which resulted in nice empty space on either
side of the text. Other buttons do not have this type of layout, so
need to have a minimum amount of padding thrust upon them.
Required breaking out into values-v17 too, so refactored common styles
into base style to make this easier.
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.
This makes it a lot easier to setup all the testing stuff. Mostly,
I'm tired of fighting Android Studio's fragility, so I want to remove
as much non-standardness as possible in the hopes of improving that
situation.
