update for obsidian 0.9.1

• new: color for graph-node attachments type
• modified : linked images default size is now contained within a 500x250px container, hover images to display in document’s max size.
• fix: fixed the tabs styling margins/padding etc. : should now work with most fonts without degradation and be more consistent
• fix : removed annoying 1 pixel transparent line at the top of the titlebar in fullscreen translucent mode
• fix : images should not be burned out when using translucency
• fix : in light mode, translucency should look better (smoother, more consistent)
