test/test-user-coder.sql: extract part of test data.

I also:
- formatted sql insert to make it shorter and more readable
- to workaround Maven's bug I moved email field at the end of the insert statement:
  + http://jira.codehaus.org/browse/MRESOURCES-104
  + http://stackoverflow.com/q/7499373/maven-resources-plugin-has-issues-with-filtering-if-there-are-odd-number-of

No functional changes.
Create database scheme, load init and test data with Liqubase.

- No more hibernate3-maven-plugin usage
- liquibase-maven-plugin runs with scheme and init-data contexts activated
- Application chooses contexts depend on active profile
- dev/*.sql files moved to liquibase/sql (to be accessible by liquibase-maven-plugin)
