Do not use Support/Compat API.

* app/app.iml: Remove orderEntry lines for appcompat-v7 and support-v4.
* app/src/main/res/values/styles.xml: Change the theme from
  Theme.AppCompat.Light.DarkActionBar to android.Theme.Light,
  which I think will actually be android.Theme.Holo.Light.
* app/sr/main/java/org/glom/app/UiUtils:
  Change R.attr.listPreferredItemPaddingLeft to
  android.R.attr.listPreferredItemPaddingLeft which seems to be
  necessary when using the non-compat theme.
* app/build.gradle: Increase minSdkVersion from 13 to 14 so we can
  use listPreferredItemPaddingLeft.
* app/src/main/java/org/glom/app/TableDataActivity.java:
  Use navigateUpTo() instead of (support) NavUtils.navigateUpTo(this, ).
