[maven-release-plugin] prepare for next development iteration
Added backup of pom file to ignore file.
Updated the commons project to have the standard api and omod subprojects.
Removed renamed api and omod folders.
Merge branch 'feature/mod' into develop
Updated to the standard git ignore file.
Updated git ignore file to ignore .idea files in common folder and removed IDEA project files.
Moved entity services from cashier module to commons.
Removed the PagingInfo.ALL because PagingInfo is not immutable.
Removed the jar file artifact that was part of the previous version of this module.
Updated packages and refactored the api class packages.
Fixed some remaining invalid references in the metadata service test.  Added the assertEntity method for the base data service implementation.
Updated the entity services and dao to use the OpenMRS object interfaces rather than the classes.
Removed old release.properties file, continued work on Constants base, and created Entity diagram.
Renamed data services to Data Accessors.
Data Accessor is a stupid name, Data Service is better even if 'service' is an overloaded term.
Merge branch 'feature/rename' into develop
Renamed entity data service priviledge classes to match renamed services.
Updated the project to create a test jar for the api module.
Added generic repository bean so that each module doesn't have to add it.
