Clean API Aliases for Custom Fields

Previously, when a custom field was created for a customer by the BambooHR support team, an API alias would be automatically created without regard to any special characters in the field name. We've now altered that creation process so that only alphanumeric characters will exist in the field aliases, thus making them more usable in API integrations.

Example: if a custom field was created with the name Favorite food/drink, the alias the system generated would be customFavoritefood/drink. Now, a field with that name will have an alias of customFavoritefooddrink - no problematic slash in the middle of the name.
