Files for EvWebView, thumbnails possible with GTK+-2.0
My last commit was supposed to have ev-web-view.c and ev-web-view.h however due to some reason I missed them last time, so here they are now. i am able to achieve thumbnails for my epub however these are of absurdly large size. Still struggling to get the webview done due to thread problems that I am encountering.
