Bug 13952: Import and export authority types

This patch amends C4::ImportExportFramework to work for authority types as well as MARC frameworks.
New file: admin/import_export_authtype.pl
Update: Ensuring we are passing the right column to the right tables.
Update2: Making the error messages the same to be consistent with patch on Bug 15665
Update3: Fixing merge conflicts
Update4: Fixing merge conflicts and removing tabs
Update5: Getting rid of warns, making sure Import and Export of default
authority will work
Update6: Merge conflicts and making sure export of default auth type
works
Update7: Fixing merge conflicts and updating buttons to bootstrap3

To test:
1) Go to Admin -> Authority types
2) Confirm there are two new columns 'Export' and 'Import' in the table
3) Click 'Export' on an existing authority type and choose a file type, click 'Export'
4) Confirm that the authority type is exported as your chosen file type. Save the file
5) Create a new authority type
6) Import into your new authority type using the file you just exported
7) Confirm you are taken to auth_tag_structure.pl
8) Go back to Authority types
9) Export your new authority type. View the exported file and confirm
the authtypecode has been updated to match the code you set for the new
auth type
10) Click 'Import' next to any existing authority type and attempt to import a file that is not XML, CSV or ODS. Confirm that this fails and you are asked to import a file of the correct file type
11) Confirm Export and Import work for the Default authority type
12) Go to Admin -> MARC bibliographic framework
13) Confirm that the 'Export' and 'Import' functions still work here as well
