We still have go-toml as a transitive dependency, and it is the way to go eventually, but we care about speed, so let us wait that one out.
Note that the issue this fixes is about taxonomies, but I guess this is a general issue for sites with many pages that uses TOML as front matter.

See #3541
Updates #3464
So you can do and get:
```
▶ ./benchSite.sh "YAML,num_pages=10"
Running with BenchmarkSiteBuilding/YAML,num_pages=10
BenchmarkSiteBuilding/YAML,num_pages=10-4 1000 1611261 ns/op 730749 B/op 6458 allocs/op
PASS
ok github.com/spf13/hugo/hugolib 8.168s
```
And change site benchmark separator to comma to make it Bash and regexp friendly, example:
./benchSite.sh "frontmatter=YAML,num_root_sections=1,num_pages=.*,tags_per_page=20,shortcodes=false,render=false"
To run a subset of these benchmark, one can do something like this:
```
go test -run="NONE" -bench="BenchmarkSiteBuilding/tags_per_page=0.*shortcodes=true.*render=false" -test.benchmem=true ./hugolib
```
Which will run without any tags, with shortcodes, but will skip rendering.
Fixes#3535
Looks to be slightly slower with the low number of section pages, but the 1000 regular pages seem to add value.
```

When we know to look into the index pages collection, do that:
```
benchmark old ns/op new ns/op delta
BenchmarkGetPage-4 51483 7072 -86.26%
benchmark old allocs new allocs delta
BenchmarkGetPage-4 71 71 +0.00%
benchmark old bytes new bytes delta
BenchmarkGetPage-4 2648 2648 +0.00%
```
This commit also returns an error if .Site.GetPage is called with the regular Page Kind, as that is currently not supported.
Fixes#3503
The unmaintained Rango frontend and the Hugopit "experiment" should be removed from the Hugo Tools/Frontends section of the documentation as they are unusable.
Rango can mess up with other dependencies installed in the Go Path as reported here:
https://github.com/stayradiated/rango/issues/4
Hugopit's developer himself stated that this is an unmaintained experiment and he seemed a bit surprised that it is included in Hugo's documentation over here: https://github.com/sjardim/Hugopit/issues/3
