Bug 11272 - add second submit button to inventory form

The inventory tool allows for 2 ways of processing files. The first
is to upload a file. The second is to generate the shelf list.
Most libraries think they have to fill in all fields because the
submit button is at the bottom of the second option. They do not.
This patch adds a second submit button under the first method to
make this clearer.

To test:

* Generate a file of barcodes for inventorying
* Before applying the patch use the file upload method to mark as seen
* Apply the patch
* Use the file upload method to mark as seen using the new submit
* Repeat the above for the shelf list method
* Confirm that inventory still works as expected with 2 buttons

Bug 11562: re-sort sysprefs.sql

The QA tools does not manage to catch error sorting on the sysprefs.sql
file if it is already badly sorted.

This patch tidies up the sysprefs file.

TEST PLAN
---------
[1] Verify that loading sysprefs.sql into an empty Koha
    database (or one whose system preferences table is
    is empty) works.

RM note: I must point out that there ZERO functionality associated
with the order that system preferences occur in that SQL script; they are
sorted solely in an attempt to reduce the likelihood of merge conflicts
during the development process.  Consequently, I dislike language that
suggests it is an "error" if sysprefs.sql happens to not be perfectly
sorted; it is at most an inconvenience.
