Initial commit
History:
- Derived from package org.pentaho.di.trans.steps.terafast
- Modified for TPT by Kevin Hanrahan (cfikevin/pentaho-kettle forked
from pentaho/pentaho-kettle)
- Moved the core pentaho-kettle classes into a plugin project
pdi-teradata-tpt-plugin (using mattyb149/pentaho-plugin-skeletons)
- Using annotations instead of plugin.xml
- Renamed the step to 'Teradata TPT Insert Upsert Bulk Loader', minor
label changes

Notes:
- To create a Marketplace zip, build with target 'package' to create
dist/TeraDataBulkLoader.zip (includes package-res/version.xml)

TODO (see also http://jira.pentaho.com/browse/PDI-10216): 
- Code review: remove system.out, print stacktraces etc.
- Build: Review the usage of pentaho-plugin-skeletons (icon in
package-res), mattyb149 updated pentaho-plugin-skeletons since it was
used
- UX: needs changes (tabs look different, some buttons/labels are too
narrow) and review  
- QA: check if variables are resolved correctly, test save to/from
repository etc.
- Doc: Finalize documentation:
http://wiki.pentaho.com/display/EAI/Teradata+TPT+Insert+Upsert+Bulk+Loader
- Check maturity level, upload to marketplace
Added .project, minor changes to README
Fixed issue with persistence of the 'Access Log File' option. This
option was not able to get stored on the file system. It worked on the
repository only.
Changed build.xml to contain the folder within the zip for the
marketplace.
