+/**
+ * Integration plugin for noscript extension
+ *
+ * Usage:
+ *   :noscript info        Shows noscript info for the current page.
+ *   :noscript popup       Opens the noscript popup.
+ *   :noscript toggletemp  Toggles scripts temporarily on current page.
+ *   :noscript toggleperm  Toggles scripts permanently on current page.
+ *
+ * Note: when the noscript popup is open, you can scroll through the items
+ * using the following standard vimperator key bindings:
+ *   j  move down one
+ *   k  move up one
+ *   l  open the sub-menu
+ *   h  close the sub-menu
+ *   g  jump to the first item in the menu
+ *   G  jump to the last item in the menu
+ * For implementation simplicity, only single character bindings are supported,
+ * so you cannot supply counts to any of the above.
+ *
+ * Tested against NoScript 1.8.6
+ *

+/**
+ * Class which provides support for noscript commands and hooks into the
+ * noscript popup to provide vimperator scrolling bindings (j,k,l,h,g,G).
+ *
+ * Note: There appears to be a bug in firefox's menupopup key bindings, where
+ * if you navigate to a sub popup (l or right arrow), and navigate back to the
+ * main popup (h or left arrow), then the menupopup seems to lose the ability
+ * to navigate back to the sub menu, and loses the ability to close the main
+ * popup via esc (an alt-tab should still close it).  This behavior is
+ * reproducable with or without this plugin.
