Subject: Introduce icons with distinct shape for connection status display on the front wui... 
X-Git-Tag: allmydata-tahoe-1.10.1a1~82^2~1
X-Git-Url: https://git.rkrishnan.org/(%5B%5E?a=commitdiff_plain;h=e499d84755fef9c540feb66558ee7a94fc32c34f;p=tahoe-lafs%2Ftahoe-lafs.git

Introduce icons with distinct shape for connection status display on the front wui page...

This replaces the status display which was only distinct by color which is a usability issue for color-blind users.  This commit includes test coverage by way of pattern matching on rendered templates.  The PNG icons are conversions of original SVG source which I've included and placed in the public domain.
