Adds joda-convert and joda-time library to build.

They have known issues, but we add them anyway to track when they get fixed.

Adds a proper design for multi-library projects and for libraries that
depend on other libraries we also test.

 When you add a new library to build, make sure it is referenced in run-all.sh (for

+The structure for each library to test is as follows:
+
+```
+libraryBuilds/
+    - common/                   - Existing directory with common build config
+    - dependsOnLibrary1/        - Existing root of a library that newLibrary depends on

+    - dependsOnLibrary2/        - Ditto.
+        - dependsOnLibrary2/    - Ditto.
+    - newLibrary/               - New directory for the root project
+        - newLibrary/           - New directory for the library itself
+            - build.gradle      - Build file containing j2objcTranslation directive for newLibrary
+        - dependsOnLibrary1/    - Soft link to ../dependsOnLibrary1/dependsOnLibrary1/
+        - dependsOnLibrary2/    - Soft link to ../dependsOnLibrary2/dependsOnLibrary2/
+        - settings.gradle       - 'include' directive for newLibrary and libraries it depends on
+        - build.gradle          - Soft link to ../common/build.gradle, contains the preamble
+        - gradlew               - Soft link to ../../j2objc-gradle/gradlew
+        - local.properties      - Soft link to ../common/local.properties
+```
+
+Every library newLibrary depends on must have its own similar structure as a top-level project,
+as illustrated by dependsOnLibrar1 and 2. Note the two level directory structure above: even if
+your library has no dependencies, the build.gradle file for the library must lie 2 directories
+below libraryBuilds1/.
 
+TODO: Create a script to setup the above structure.
