Alternative source only install

[gradha]

Instead of using maven I was experimenting on how to use droid-fu as a source dependency rather than jar. I figured out how to do it (gradha@2461c7e) but unfortunately in the process I had to remove the map related activities and assertions tests because I was getting compilation problems (gradha@a78d7c6).

This is not a big deal for me since I don't plan to use anything map related, but I wonder if the map activity compilation issues are due to the way I'm including the source or they are related to the other issues you have opened in github about including the google libraries inside the jar.

The errors related to the MapActivity class and others also appear when generating the documentation (see #38), here's some of them:

Constructing Javadoc information...
droid-fu/src/main/java/com/github/droidfu/activities/BetterMapActivity.java:21: package com.google.android.maps does not exist
import com.google.android.maps.MapActivity;
                              ^
droid-fu/src/main/java/com/github/droidfu/activities/BetterMapActivity.java:22: package com.google.android.maps does not exist
import com.google.android.maps.MapView;
                              ^

Any pointers on how to fix these problems are welcome.
