Bug 34395

While testing bug 33909, I had to look at all the pages in the administration module. In doing so, I found some inconsistencies between the various pages. 

For the Authority types page, here is what should be changed to make it consistent with the other pages in the module:

Page title
- Add authority type code to Modify X in page title (e.g. Modify authority type 'CHRON_TERM')
- Add authority type code to Confirm deletion of authority type
- Add a level with the When viewing the MARC structure of an authority type, with the framework code (e.g. "Authority MARC framework for CHRON_TERM")
- Add the tag number when modifying a tag
- When deleting a tag, change 'Confirm deletion' to "Confirm deletion of tag Y"
- When viewing/editing subfields, add a level for the framework and a level for the tag
- When editing subfields, use 'Modify'


Breadcrumb
- Add authority type code to Modify X in page title (e.g. Modify authority type 'CHRON_TERM')
- Add authority type code to Confirm deletion of authority type
- When viewing the MARC structure of an authority type change the level from "CHRON_TERM Framework" to "Authority MARC framework for CHRON_TERM" (or MARC structure?) 
- Add the tag number when modifying a tag
- When deleting a tag, change 'Confirm deletion' to "Confirm deletion of tag Y"
- When editing subfields, change 'Edit MARC subfields constraints' to "Modify MARC subfields constraints for tag 000"

Page header
- The styling for the header of the New X page is different from the rest<
- The styling for the header of the Modify X page is different from the rest
- Add authority type code to Modify X in page title (e.g. Modify authority type 'CHRON_TERM')
- Add the tag number when modifying a tag
- When deleting a tag, change 'Confirm deletion' to "Confirm deletion of tag Y"
- When viewing subfields, change "Authority MARC subfield structure admin for 035 (authority: CHRON_TERM)" to "Authority MARC subfield structure for tag 035 (CHRON_TERM authority type)" (I'm unsure about how to mention the authority type in the header, but I definitely don't like the colon!)
- When editing subfields, change 'Edit MARC subfields constraints for field 035 authority CHRON_TERM' to "Modify MARC subfields constraints for tag 035 (CHRON_TERM authority type)" (I personally prefer "field" to "tag", but tag is used everywhere else) (I'm also unsure about how to mention the authority type in the header)
