r51402: ace:dateTimeEntry, added ability to define multiple ranges of min/max dates via the new 'selectableDateRanges' attribute

This is the TLD documentation for the 'selectableDateRanges' attribute, explaining how it works and other considerations:

Specifies a number of ranges of selectable dates. The value can be a number of date strings separated by commas, a List of Date objects or an Array of Date objects. These dates are taken in pairs to delimit a range; the first date in the pair is the start date, and the second date in the pair is the end date of that range. These dates are inclusive. If the first date of the pair is null, the empty string, or an invalid date, then the range will be considered to be from any date in the past up to its end date. Likewise, if the second date of the pair is null, an empty string, or an invalid date, then the range will be considered to be from its start date to any date in the future thereafter. If the dates are specified as strings, they are parsed according to the 'pattern' attribute of this component. Dates are taken literally, as they appear in the calendar, without regard for time zones. This attribute takes precedence over the 'mindate', 'maxdate', 'minDateTime', and 'maxDateTime' attributes. This attribute is only used to specify date ranges, not date-time ranges.

Re-open to backport to the EE 3.3. maintenance branch.

r51444: backported to the 3.3 EE maintenance branch

Re-opened to add new showcase demo for this feature.

r51453: added selectable date ranges demo to the showcase

Let's re-arrange the demo layout as follows:

• Make each range Start/End fit on one row
• Remove the "Submit Date" button and use ajax to auto submit each selected date.
• Add some vertical whitespace between the top "Selected Date" box, the date range configuration box (add a border around it), and the date entry component.

r51459: modified approach to make sure date ranges are inclusive
r51460: committed demo improvements described in previous comment
r51461: committed fixes to the EE 3.3 maintenance branch

Showcase Demo Review Notes

• Change the "Selected Date:" label for the dateTimeEntry comp to "Select a Date:"
• Can the whitespace between the labels and entry fields be shortend?

r51643: modified label; reduced space between labels and inputs
