Improve the bulk upload of Indicators

These are some small improvements I've made to the bulk upload of Indicators to make it more user-friendly:
- Error and success messages were not always displayed cleanly. Do a better job of indicating what the error was and which row caused it.
- Continue processing next row upon error
- Allow upload without all commas in each row
- Do not add Indicator if given domain is invalid
- Notify if protocol prefix is not included for URI - URL upload
- Accept Indicator Type without proper spacing around the dash

We found it useful to be able to add Actions to an Indicator in the bulk upload, so I added that. I also noticed that while Tickets were added to the bulk upload, the text at the top of the two bulk upload dialogs (blob and CSV) didn't mention Tickets, so I updated that text.

The other commits are related and fairly self-explanatory.
