This changes the format of the localization data to enable apps to trivially lazy-load translations. It also adds --locales to the build scripts to allow app developers to choose the compiled-in locales. The generated output now goes into dist/ and is not checked into revision control. Finally, it adds "description" and "meaning" fields to the source messages to allow us to more easily integrate with a context-aware human translation service. The "description" field provides application context for the translator, while the "meaning" field provides linguistic disambiguation for words with multiple meanings or parts of speech in the original English. Because the translation service wants to collapse messages with identical text, we had to merge several messages together. To this end, we have removed the prefixes "ARIA_LABEL_" and "LABEL_" from the messages themselves and collapsed what remained. Issue #1688 Change-Id: I24c17e71c73f6663cf123cfdba118c486fa80ecc
