Added note about testing templates in the template tool
Added section about how `|` has priority over non-bracket operators
Some minor changes to steer people towards `states.('...')` rather than `states...state`.
As somebody pointed out on the forum, using different examples adds confusion. Updated both styles to use the same contents, so it's clearer what's going on.
* FOR DISCUSSION - improving the Securing docs
This probably needs some back and fore to work out what the projects want here, but I thought I'd give it a first pass through to turn this from a "wall of things" that seem equally important into something hopefully more digestible. Particularly as some of the things look like you should do all of them, but they're actually mutually exclusive, or functionally identical.
I've tried to break it into things that people must do (here's the basic minimum) and things they should consider if they want to make it more secure. I've also tried to steer people towards `cloud` where it'll work for them, and if they just want remote access to the UI to use a VPN or Tor (I moved the SSH tunnel option last because it's the most complicated to set up of the three).

Reworking the customize docs:
1. Add information on using the UI to change the entity ID and name (where supported)
2. Document the use of the UI to customize
3. Rewrite the configuration block to use the new configuration block standard
4. Move the manual editing section towards the end

Taking out the "new and experimental" note - we're a dozen releases on, it's hardly new and seems to be (from a feature sense) stable.
Re-written para 2 to reflect that HA needs shut down, and that 0.75 introduced the "future" UI. Re-written the supported components list because it's horribly out of date, and without trawling the code it's impossible to know what's supported.
Added examples for whitelist_external_dirs as I found it difficult to figure out
a) it had to follow homeassistant:
b) drop the last slash for the directory i.e. /tmp/exampledir NOT /tmp/exampledir/
