Update to 0.52

Changelog:
The two big new items in this release is Inline Shortcodes and Consolidated File \ 
Caches. In Hugo we really care about build speed, and caching is important. With \ 
this release, you get much better control over your cache configuration, which \ 
is especially useful when building on a Continous Integration server (Netlify, \ 
CircleCI or similar). Inline Shortcodes was implemented to help the Bootstrap \ 
project move their documentation site to Hugo. Note that this feature is \ 
disabled by default. To enable, set enableInlineShortcodes = true in your site \ 
config. Worth mentioning is also the new param shortcode, which looks up the \ 
param in page front matter with the site's parameter as a fall back.

This release represents 33 contributions by 7 contributors to the main Hugo code \ 
base.
@bep leads the Hugo development with a significant amount of contributions, but \ 
also a big shoutout to @moorereason, @emirb, and @allizad for their ongoing \ 
contributions.
And a big thanks to @digitalcraftsman and @onedrawingperday for their relentless \ 
work on keeping the themes site in pristine condition and to @kaushalmodi for \ 
his great work on the documentation site.

Many have also been busy writing and fixing the documentation in hugoDocs,
which has received 10 contributions by 4 contributors. A special thanks to \ 
@budparr, @bep, @allizad, and @funkydan2 for their work on the documentation \ 
site.

Hugo now has:

    30595+ stars
    441+ contributors
