Add the ability to dynamically re-assign the static "folder" (although I realised, I can use symlink as workaround)

[rubyFeedback]

We can set the public "folder" via set such as:

set :public_folder, __dir__ + '/static'

I would like to change the public folder, specifically to serve some video files that are accessed only via /video/.

(I suppose I could use symlinks to the public "folder" but I find it more elegant to just re-assign the public "folder" directve.)

Right now I am not sure how this can be done. I thought about doing so within the route, but set() does not work there, as it only works on the toplevel. Could this functionality be added, and also documented in the official sinatra tutorial?

I'd like to use another public directory depending on which sub-functionality is to be used, e. g. one directory for when working with .pdf files, another one for when working with multimedia files and so forth.

Edit: Hmm, symlinks work, so I have a workaround, even though it is not very elegant. It works on Linux, though, not sure if that would work on windows. So I'd still have that use case on windows. Another alternative is to probably just set the public directory to the root of the filesystem or where I keep those video files (e. g. /home/x/video/ also on windows, or some other subdirectory). Not elegant but I guess this here is semi-solved.
