Added multiroute prerendering

[framp]

This PR adds support for prerendering a set of routes instead of limiting to / (as per #185 (comment))

In order to use this functionality, you have to add a prerender-urls.json file, which contains the set of routes you want to render.
The format for the file is an array of objects with a url key and an optional title key which will override the title.
Eg:

[{"url": "/", "title": "Homepage"}, { "url": "/route/random"}]

I've added a --prerenderUrls option which let you change the path of the prerender-urls.json to whatever you like.

Feedbacks appreciated :)

Dear @framp with the following URLs configuration for the included sample:

[ { "url": "/", "title": "Homepage" }, { "url": "/profile ", "title": "Overriden Profile Title" }, { "url": "/profile/john ", "title": "John's Profile" } ]

I'm getting two profile folders pre-rendered:

Does this seem right?

[framp]

@carlosagsmendes it does not seem right and it's not possible on a filesystem level.
I suppose it's a visualisation bug in your editor, probably triggered by indexing files in the same directory at a close time.

Do you mind doing a tree or ls -hall from the terminal in your build directory or restarting your editor?

Here's the output after deleting the folder and doing a new build:

One thing I noticed is that if I do a "Hard Reload" on Chrome on the https://localhost:8080/profile/ Url I don't get the correct page rendered:
