v0.4.3-alpha : Automatic dependency resolution

New functionality:

• Automatic dependency resolution for Maven jars and Gradle projects #420
• Build external Java libraries (with source) into standalone native libraries #431
• Proper limitation of functionality on non-Mac platforms #396
• Embedded docs and versioning info for easier debugging #395
• Specify a subset of J2ObjC libraries to link to #433
• Map individual Java files to a separate version used only for J2ObjC translation #455
• Projects no longer need to guarantee the Java plugin is applied before the J2ObjC Gradle plugin #453

Breaking changes/functionality:

• Default supported architectures reduced to modern devices only (arm64, armv7, x86_64) #448
• Production (main sourceSet) and test code are now translated and built separately #474
• J2objcConfig.filenameCollisionCheck is now named forceFilenameCollisionCheck,
  and defaults true only when using --no-package-directories #470

Code quality:

• A small number of common open-source Java libraries are being built end-to-end with the J2ObjC Gradle plugin
• Continuous integration on Mac #406 and on Windows #401
• Added end to end tests on OSX (running j2objc) #409 #411 etc.
• Unit tests pass on Windows #404
• Prevent publishing of bad releases #395 #398
• Docs updates (various)
