I realise that these meta tags aren't doing any harm - but they are not needed at all and take up a few bytes of the page loading.
- The `HandheldFriendly` meta tag was used for a very old version of BlackBerry.
REF: https://developer.blackberry.com/playbook/html5/documentation/handheldfriendly.html
- The `MobileOptimized` meta tag was used for a very old version of Windows Mobile 5 / 6 (before even Windows Phone 7, 8 and Windows Mobile 10!).
Before this commit, due to a bug in Go's `text/template` package, this would print different output for typed nil interface values:
```
{{ if .AuthenticatedUser }}User is authenticated!{{ else }}{{ end }}
{{ if not .AuthenticatedUser }}{{ else }}}User is authenticated!{{ end }}
```
This commit works around this by wrapping every `if` and `with` with a custom `getif` template func with truth logic that matches `not`, `and` and `or`.
Those 3 template funcs from Go's stdlib are now pulled into Hugo's source tree and adjusted to support custom zero values, e.g. types that implement `IsZero`.
This means that you can now do:
```
{{ with .Date }}{{ . }}{{ end }}
```
And it would work as expected.
Fixes#5738
Closes#743
- Added note that the content directory of an ExampleSite is now inherited from the HugoBasicExample for security reasons.
- Removed placeholder text for example README outline since there is no such outline.
- Instead I updated some of the points of what should be included in a README

Before this commit `where` would produce an error and bail building the
site. Now, `where` simply skips an element of a collection and does not
add it to the final result.
Closes#5637Closes#5416
Old code always returned "." or "" (if filepath.Ext(filename) returned ".").
Now it properly trims the prefix.
