Finished first pass of updating to liquibase 3.0.7, updated to Gradle 1.7
Rolled back change to the 'include' attribute of a DatabaseChangeLog.  We lose the ability to get changeLogs from subdirectories and zip files, but we restore the ability to process files in order
Worked around Liquibase bug CORE-1293, which was corrupting sqlFile checksums
Added descriptions of tasks, created a test file for sqlFile changes and fixed a test
Fixed where clause functionality in the delete and update change sets
Upon further review, implementing 'where' clause functionality as an attribure is inconsistent with the XML DSL.  The ruling on the field is overturned
Updated the README with important update information.
Merge pull request #39 from stevesaliman/master
