2.7.0

1. Undid dialog max width changes again, to what they were before they looked small. Added maxWidth setter function that you can use to custom dialog max widths if you wish, although it's discouraged.
2. Added a dialogWrapContent parameter to customView(...) which instructs the dialog to set its max width to the measured width of your custom view.
3. The datetime dialogs use the dialogWrapContent parameter above, which fixes how they look in landscape etc.
4. You can set a maxDate for date picker dialogs.
5. Misc. bug fixes and code cleanup.
