There are currently several Params and case related issues floating around in Hugo.
This is very confusing for users and one of the most common support questions on the forum.
And while there have been done some great leg work in Viper etc., this is of limited value since this and similar doesn't work:
`Params.myCamelCasedParam`
Hugo has control over all the template method invocations, and can take care of all the lower-casing of the map lookup keys.
But that doesn't help with direct template lookups of type `Site.Params.TWITTER_CONFIG.USER_ID`.
This commit solves that by doing some carefully crafted modifications of the templates' AST -- lowercasing the params keys.
This is low-level work, but it's not like the template API wil change -- and this is important enough to defend such "bit fiddling".
Tests are added for all the template engines: Go templates, Ace and Amber.

Add imageConfig function which calls image.DecodeConfig and returns the height, width and color mode of the image. (#2677)
This allows for more advanced image shortcodes and templates such as those required by AMP.
layouts/shortcodes/amp-img.html
```
{{ $src := .Get "src" }}
{{ $config := imageConfig (printf "/static/%s" $src) }}
<amp-img src="{{$src}}"
height="{{$config.Height}}"
width="{{$config.Width}}"
layout="responsive">
</amp-img>
```
This commit adds a `GitInfo` object to `Page` if `EnableGitInfo` is set.
It then also sets `Lastmod` for the given `Page` to the author date provided by Git.
The Git integrations should be fairly performant, but it adds "some time" to the build, somewhat depending on the Git history size.
If you want, you can run without during development and turn it on when deploying to the live server: `hugo --enableGitInfo`.
Fixes#2102
changes:
- in hugolib/page.go, `func permalink` and `func TargetPath`
Fixed the attempt to *replace* the extension of something
that was *already* a basename.
- in source/file.go, `func NewFile`
added check for allowed languages before translating filename
Fixes#2555
All config variables starts with low-case and uses camelCase.
If there is abbreviation at the beginning of the name, the whole
abbreviation will be written in low-case.
If there is abbreviation at the end of the name, the
whole abbreviation will be written in upper-case.
For example, rssURI.
The gain, given the "real sites benchmark" below, is obvious:
```
benchmark old ns/op new ns/op delta
BenchmarkHugo-4 14497594101 13084156335 -9.75%
benchmark old allocs new allocs delta
BenchmarkHugo-4 57404335 48282002 -15.89%
benchmark old bytes new bytes delta
BenchmarkHugo-4 9933505624 9721984424 -2.13%
```
Fixes#2495
Also refactor the rendering pages test to accept more than one page source per test run, which wasn't really needed for this issue, but may be in the future.

Maps in Viper, Hugo's config backing store, is now properly lower-cased not just on top level, the current situation.
While this is mostly a good thing, as you don't need to know the original casing to look up a value, it will be breaking for people doing direct lookups in the ´Site.Params` map.
We will try to find a solution to this "breakage", but the recommended method to get params values is via the `.Param` methods.
This method is now implemented on `Node`, `Page` and `Site` and is case-insensitive:
* Use `.Param "someKey" ` if you want page param with fall back to site param if not found on page.
* Use `.Site.Param "someKey"` to get a site param

This change adds a canonical alias.html template that is used for page
redirects, and passes the page as data to the template under .Page

Add DocumentName (path to the file being rendered) to RenderingContext
and use that information to include the path in the error print.
