[threeten-dev] zidtext parser

[Xueming Shen]

Here is the first try of adding the zidtext parser

http://cr.openjdk.java.net/~sherman/jdk8_threeten/zidtext_parse

It appears the zoneid parser works as expected.

But I'm not sure what the best way is to handle the "general" zone
names, such as "Mountain Standard Time", "Western European Time".
We have m:1 mapping when printing, what should we do for the
1:m parsing? Pick a "representable" zid and hardcode the mapping?
