Infrastructure for doing test driven development to support multiple repo dev.

The new test skeletons right now update three different repos
in different configurations. They do so such that the order of updates
changes and therefore the way in which conflicts between repos are
dealt with are tested.

They should all have the same result (though I'm not sure exactly what
that should be yet).

+# Multiple Repos Test
+
+This covers the three indexes:
+ * multiRepo.normal.jar
+ * multiRepo.archive.jar
+ * multiRepo.conflicting.jar
+
+The goal is that F-Droid client should be able to:
+
+ * Update all three repos successfully
+ * Show all included versions for download in the UI
+ * Somehow deal nicely with the fact that two repos provide versions 50-53 of AdAway
+
+## multiRepo.normal.jar
+
+ * 2048 (com.uberspot.a2048)
+   - Version 1.96 (19)
+   - Version 1.95 (18)
+ * AdAway (org.adaway)
+   - Version 3.0.2 (54)
+   - Version 3.0.1 (53)
+   - Version 3.0 (52)
+ * adbWireless (siir.es.adbWireless)
+   - Version 1.5.4 (12)
+
+## multiRepo.archive.jar
+
+ * AdAway (org.adaway)
+   - Version 2.9.2 (51)
+   - Version 2.9.1 (50)
+   - Version 2.9 (49)
+   - Version 2.8.1 (48)
+   - Version 2.7 (46)
+   - Version 2.6 (45)
+   - Version 2.3 (42)
+   - Version 2.1 (40)
+   - Version 1.37 (37)
+   - Version 1.35 (36)
+   - Version 1.34 (35)
+
+## multiRepo.conflicting.jar
+
+ * AdAway (org.adaway)
+   - Version 3.0.1 (53)
+   - Version 3.0 (52)
+   - Version 2.9.2 (51)
+   - Version 2.2.1 (50)
+ * Add to calendar (org.dgtale.icsimport)
+   - Version 1.2 (3)
+   - Version 1.1 (2)
