Bug 11142 - Update Bootstrap theme's place hold form to match the new version in prog

The update to the prog theme's place hold page (Bug 10836) happened
after the Bootstrap theme's place hold form had already been converted,
so it lags behind. This patch applies the changes made to prog to Bootstrap.

To test, switch to the Bootstrap theme and follow the test plan from Bug
10836:

Place single and multiple holds under various conditions:

- Items which are not available to be place on hold
- With OpacHoldNotes on and off
- With OPACItemHolds on and off
- With OPACAllowHoldDateInFuture on and off
- With IndependentBranches on and off
- With JavaScript disabled

Test setting hold notes, holding specific copies, and setting hold start
dates. When setting a hold start date and hold expiration date, the two
datepickers should work together to prevent invalid date combinations
(dates after today, expiration dates which precede the start date).
