Weather plugin should use colors and possibly icons

[theepicsnail]

Look into unicode icons, see if they are readable. Decide on some color schemes (temperature dependent, weather dependent, etc..). For temp dependent colors, the high and lows of the day would be of interest, verses just the current temperature.

Here are some possible Unicode characters to use.

☀
BLACK SUN WITH RAYS
Unicode: U+2600, UTF-8: E2 98 80

⛅
SUN BEHIND CLOUD
Unicode: U+26C5, UTF-8: E2 9B 85

☁
CLOUD
Unicode: U+2601, UTF-8: E2 98 81

☇
LIGHTNING
Unicode: U+2607, UTF-8: E2 98 87

☔
UMBRELLA WITH RAIN DROPS
Unicode: U+2614, UTF-8: E2 98 94

Under OS X 10.8.4 and Chrome 30.0.1599.69, only the sun, cloud, and lightning characters render, while all of them work under Safari 6.0.5 (8536.30.1)—some even with emoji. That is to say, whether a Unicode character is readable really depends on the client, and I don't think that should be reason not to include them. Worst case they see a little box and are motivated to get Unicode working. 😉
