Feature - Send templated email process - initial commit of the feature that uses the acs commons email api to send an email via a workflow process
created AuthorUIHelper to de-couple functionality of generating a link to a page or asset in the author environment. Provides an OSGi configuration to set Touch UI vs Classic UI urls

updated SendTemplatedEmailProcess to use AuthorUIHelper and SendTemplatedEmailHelper to do the bulk of the 'work'
refactored to create AbstractSendTemplatedEmailProcess.java so that other implementing classes can override logic for recipients of emails and add additional parameters to the email parameter list
must have added whitespace by accident, reverting to master commit
fixed whitespace, replaced tabs with spaces
