Doc: selected browser function

[michael-heerdegen]

Hi,

in the header and the doc of `helm-dictionary-browser-function', we should say more clearly how the browser function is selected. The docs are currently incomplete and inconsistent.

This is how it works:

• use the value of `helm-dictionary-browser-function' if non-nil, else
• use the value of `browse-url-browser-function' if non-nil, else
• let helm find a suitable browser (via `helm-browse-url-default-browser-alist').

Also the tag in

      (const      :tag "Currently configured default for Helm"
                     :value nil)

is misleading. We don't need to give a complete description in the :tag, we could just use "default" and explain in the docstring what that means.
