Bug 15451: Rewrite the csv profile tool script

This page was inconsistent with the other admin and tool pages.
The 2 tabs 'New profile' and 'Edit existing profile' were useless, the
ergonomic needs to be revisited.
This patch applies the same script/page structure as others: by default
a table containing all csv profiles is displayed with 2 action links:
edit and delete.

Test plan:
1/ Create 1+ CSV profiles, with different types (marc and sql)
2/ Update some values using the Edit link
3/ Delete a CSV profile

Note: When deleting a CSV profile, it would be great to warn the user if it is
used.
