bmany: Support Firefox 40

[gardejo]

Hello,

It seems like bmany plug-in has a few following problems on recent (40+) Firefoxes. This Pull Request tries to solve them.

I would be grateful if you could merge it. Thank you for your cooperation.

1. Bookmark properties dialog

bmany cannot invoke Bookmark properties dialog by Edit selected bookmark item menu item (edit-bookmark command). It is because PlacesUIUtils.showBookmarkDialog() now takes a node of places, not an node#itemId.

  2. Doubly-opening a URI

bmany doubly opens a URI in a list item.

I am awfully sorry but I am not find out its fundamental cause. But the latest KeySnail 2.7.0-signed only supports Firefox 34 to 41. So I simply removed the compatibility codes for legacy Firefoxes.

3. Fallback for keywords

Regrettably, Firefox 40+ removes the keywords column from the library. So I simply added fallback codes.

  4. Caching timing of bookmarks in the toolbar

From the very beginning (198bfd26feb497a6b053e112d64abce9e5864caf), we had been mistaken the condition of the cache exists or not. So I fixed it.

I am grateful to have you handle that right away. And I am sorry to have omitted consideration of minVersion in PLUGIN_INFO.
