-Adds new repack_options variables
-Updates pragma to output numeric_id instead of resource_id
-Updates find_used_resources.py to filter for numeric_id
To use the existing system you need to do following steps:
1. Remove out directory (we need to do a clean build)
2. Append " enable_resource_whitelist_generation=1" to GYP_DEFINES
3. Run gyp
4. Build your target (e.g. chrome_shell_apk) saving output to a file
(e.g. build.txt)
5. cat build.txt | tools/resources/find_used_resources.py > whitelist.txt
6. Append " repack_options='--whitelist /path/to/whitelist.txt'"
7. Run gyp
8. Build your target again.
9. ???
10. Profit!!!
