Double input of a Staticman parameter

[VincentTam]

In #224, Hugo's cache has been introduced so that user only needs to input reCAPTCHA parameters only once in the Staticman config file.

minimo/layouts/partials/comments/staticman/form.html

Line 12 in d2587aa

{{- $reCaptcha := $staticman.comments.reCaptcha | default ( dict "enabled" false ) -}}

Nonetheless, users have to input the branch twice, once in the theme config file and once in the Staticman config file. A little line like

{{- $branch := $staticman.comments.branch -}}

would make the whole thing consistent with your arguments for calling parameters from the Staticman config file.
