[Feature Request] Add example scripts and templates for the Design Patterns

PRs #232, and #255 are a first cut at this. Many of the design patterns are not applicable to scripted automation and even more can be easily implemented with one of these already existing modules and scripts (e.g. Cascading Timers can more easily be implemented with the Gatekeeper module). Time of Day will be submitted soon which uses Ephemeris to identify day types allowing for different times of day based on the day type. I want to wait until after tomorrow (Election Day) to make sure it handled holidays properly without being "tricked" with a custom holiday list.

Even though they are not design patterns, I would apply PS #233, #234, #237, and #257 as generally fitting into this category as well.

All of the above that consist of scripts and not just a module still need to be reviewed and merged and I haven't started looking at templates yet. It's not clear to me how to go from a Rule JSON to a Template JSON and how importing it and configuring a Template works with the current PaperUI. Do we need to wait for OH 3 to manage this?
