Change Recent Comments Number Input to type="number"

[mordauk]

In order to be consistent with the rest of the dashboard, the "Number of comments to show:" input field in the Recent Comments widget should be changed to type="number" in order to add the up/down arrows.

Patch for both dashboard recent comments and main widget

Also to be consistent, these should probably have min and step attributes specified - 1 for both, seems like. 0 on the Dashboard tells you there are no comments yet, and 0 in the widget just gets you the default of 5.

Updates type to "number" and adds step and min attributes. Changes class to small-text

Changes type to number and adds min / step attributes.

.small-text on the widgets one makes the input just wide enough to push to a second line, at least on OSX in English. Not the end of the world, but wondering if maybe we should create a .tiny-text class? Would be something like 22965.diff​.

I'm all for a new .tiny-text class. The small-text class has always seemed just a little too large for input fields that will never (in all sane applications) go over two digits.

2 quick comments on 22965.diff​:

1) Having the input push to a new line doesn't seem worth fixing to me, as the title field just above wraps to a new line as well. It looks almost more uniform to me on a new line. Also, even with a new .tiny-text class, won't it still likely wrap for some translations?

2) The padding for the number selector looks off (not sure we can do anything about that):

[helen]

I'm not nearly as concerned about the pushing to a new line so much as just providing more generic classes for general use. Not pushing to a new line in this instance would be good to keep it looking the same way it does now, but more of a bonus than a necessity.

Refresh of Helen's patch. Additionally aligns the number selector vertically.

Widgets: use input[type="number"] for the number prop in the Recent Posts and Recent Comments widget forms.

Props helen, obenland, mordauk.
Fixes #22965.
