Opera Speed Dial like chrome

Opera Speed Dial is an compact eyecandied bookmark list with thumbnails of the webpages in it. Chrome and Safari adopted it and with firefox there is a plugin offering this functionality. Because with luakit it is possible to create custom chromes, we can add this feature, too.
For creating the screenshots you will need external tools:
- CutyCapt, or any other tool that can render websites to images and
- ImageMagick's mogrify tool to crop and resize the website screenshots.
The bookmarks will be saved to a favourite file, which should be located at ~/.local/share/luakit/favs. The script below will fail if this file does not exist. Every line of the file describes a bookmark:
[url] [thumbnail-path] [refresh-on-show] [title]
If the thumbnail-path is "none" or refresh-on-show is "on", the script will create a thumbnail as the chrome is shown. For example:
http://luakit.org none no luakit - browser framework
http://reddit.com/r/programming none yes Programming reddit
local chrome = require "chrome"
local cutycapt_bin = "~/.bin/CutyCapt"
local cutycapt_opt = "--min-width=1024 --min-height=768"
local mogrify_bin = "/usr/bin/mogrify"
local mogrify_opt = "-extent 1024x768 -size 240x180 -resize 240x180"
