1. Fixed file/folder chooser dialog crash
2. Build Tools 25.0.1, Google libs 25.1.0, Gradle and Gradle plugin updates
3. Fixed "\n" passed in string to .content() not working, due to auto-HTML parsing.
4. Extension filter in file chooser compares file names at the end, rather than as a whole (endsWith vs contains).
5. Added .choiceWidgetColor(ColorStateList) method to the Builder, which allows you to specify a custom ColorStateList that is applied to theme check boxes and radio buttons in single/multi-choice dialogs. .widgetColor() is still used otherwise.
6. Added .tag(Object) to the Builder and getTag() to MaterialDialog.
7. Sample project uses Jack and Java 8, all sample code uses lambdas in callbacks.
8. When applying a custom background color to dialogs, there will no longer be unthemed pixels on the rounded corners.
9. Some other edge case bug fixes and logic tweaks.
