[Enhancement]: When editing series set focus on inputs

[wtanksleyjr]

Describe the issue

When attempting to edit a series in a book, I expect to click the button and then type; but the resulting typing winds up in some other field.

Workaround: be paranoid, remember to always look for the blinking cursor before typing.

Proposed solution: when the Series box pops up, the keyboard focus should move to the Series box, either in the title (for new series) or in the index (for existing series).

Steps to reproduce the issue

1. Go to Details tab in a book.
2. Click in Description so you can see your cursor.
3. Click the + under Series to add a series, or click the pencil icon on an existing series. Notice that the Series modal dialog pops up, and so the Description is now dimmed; but contrary to the implication of the dimming, the cursor is still in the Description and is blinking.
4. Then begin typing; the input goes into the Description field (I expected it to go into the Series field).
