There are no messages on adding and deleting patron category.
If an error occurs and the data is not inserted, the interface does not
alert the user.
This patch adds a message block to alert the user if something wrong
happened.
Test plan:
1/ Create a patron category PATCAT. You should get a confirmation
message.
2/ Try to create another patron category with the same code. You should
get an error message
3/ Delete the patron category PATCAT. You should get a confirmation
message.
Confirm there is no regression on this form (try update an existing
patron category too).
Followed test plan, works as expected.
