Custom Field Mappings Support for Lightning Components (#749)

* Added support for custom field mappings in JavaScript via a new function setField() in logEntryBuilder.js
  * This is equivalent to the Apex method overloads setField() in LogEntryEventBuilder.cls that were introduced in v4.13.14

* Updated the demo lighting components in recipes metadata to set a custom field on LogEntry__c
  * This provides a quick & easy way to verify that the functionality works for lightning components

* Updated README.md to have details about using custom field mappings in JavaScript (lightning components)
