* Add date and tz functions to templates
This commit adds the date and tz functions to templates. This means
users can now format time in a specified format and also change
the timezone to their specific locale.
An example of how these functions work, and can be composed together,
can be seen here:
{{ .StartsAt | tz "Europe/Paris" | date "15:04:05 MST" }}

This commit fixes data corruption in templates that use the title
function as it used a shared cases.Title when casers should not
be shared between goroutines. When templates that used the title
function were executed at the same time, data corruption would occur
in the text that was being cased. This is fixed using a separate
caser for each function call.
Add tests to assertDefaultFuncs are thread-safe

This commit implements the Stringer interface for Pairs and KVs.
It changes how Pairs are printed in templates from
map[name1:value1 name2:value2] to name1=value1, name2=value2. KVs
work similar, but are first sorted into pairs before being printed.

* Automate CSS-inlining for default HTML email template
The original HTML email template was added in `template/email.html`.
It looks like the CSS was manually inlined. Most likely using the
premailer.dialect.ca web form, which is mentioned in the README for
the Mailgun transactional-email-templates project. The resulting HTML
with inlined CSS was then copied into `template/default.tmpl`. This
has resulted in `email.html` and `default.tmpl` diverging at times.
This commit adds build automation to inline the CSS automatically
using [juice][1]. The Go template containing the resulting HTML has
been moved into its own file to avoid the script that performs the CSS
inlining having to parse the `default.tmpl` file to insert it there.
Fixes#1939.

Since it's impossible to create a string slice in a Go template by
default, add a function to work around this problem.
The use case is to make it easy to call KV.Remove with an arbitrary
slice inside a template.

* do not split receiver by slash
I'm not sure why this was originally done, because a slash seems to be perfectly
valid in a receiver definition. The only issue i encountered was that linking
from a fired alert was not working, because of the splitting performed here.

* urlquery escape Receiver by default for URL
If Receiver is allowed to contain slashes and other special characters
we need to percent encode them properly.

It turns out that 'title case' is a thing in unicode,
in the same way upper/lower case is.
What our users will want is the first character of a word
being titlecased, which `title` will do.
- Cut back to bare minimum to make the rest simpler
- Consistency in config naming
- Have one data strucutre that's the same for all templates
- Pass in common labels to templates
- Support templates almost everywhere
- Support multiple SMTP recipients
- Support non-ASCII SMTP headers
- Handle colour logic via templates
- Make $subjects have consistent output, go maps aren't sorted.
- Make tests pass when v6 is disabled
No longer update components based on a new configuration. Generally,
destroying and recreating has no performance impact and is less
error-prone.
This also removes the Reloadable interface and simplifies the entire
startup contraption.
