altosdroid: Import initial versions of XML and Java for Tab content

* Includes TabsAdapter class borrowed from Support Library sample code
* New "GoNoGoLights" class for dealing with the red/green/gray LEDs
* extra required strings in strings.xml
* Couple of support functions in AltosDroid.java
* rudimentary Maps tab - does nothing at present.
