adm/style/acp_users_overview.html produces an unmatched </form> tag when viewing your own user.

The template conditionally creates the form with the ID "user_delete" only if viewing a user different to your own user by switching on "IF not S_OWN_ACCOUNT". The closing </form> tag is outside this switch, leaving this tag unmatched when viewing your own user.

To fix this bug, I suggest to move the closing </form> tag into the switch statement.
