/*
* This code comes from wxWebView sample webview.cpp and is modified to be used in Kicad
* the wxWidgets sample code webview.cpp is under wxWindows licence (author Marianne Gagnon)
*
* Webviewer runs in a dialog to allows an user to select a list of URLs which are .pretty library
* folder accessible from http or https using the Github plugin.
*
* The Web viewer just return a list of URLs selected from the context menu (command copy link)
* when mouse cursor in on a http link.
* URLs strings are filtered
* Only URLs starting by "http" and ending by ".pretty" can be currently selected and stored in fp lib list
