Complete:
--------
- src/* documentation resources moved to 'docs' subproject
- docbook sources upgraded to Docbook 5
- formatted all docbook sources to strip tab characters and
eliminate trailing whitespace
- all projects compile and test successfully
- all artifacts upload successfully to s3, static.sf.org, etc.
Remaining:
---------
- documentation L&F needs work. CSS, images, and highlighting aren't
hooked up properly
- spring-integration-jdbc codegen bits in Maven POM need to be
transcribed into gradle
- dependencies that were optional or provided scope in maven are
currently 'compile' scope in Gradle. Need to figure out support
in Gradle to fix this.
- run through Eclipse classpath and project generation scenarios
- delete all Maven artifacts
