Make Sandcastle tolerant of JSDoc's new static prefixes.

[emackey]

Fixes #2757. There are two parts to this fix.

1. In the generated types file, the keys have the prefixes removed (since the keys match lowercase snippets of alphanumeric source code, sans punctuation), but the values are real URLs with the prefixes intact. Thus, fragments of text can be matched to both static and non-static member URLs.
2. Sandcastle's presentation of the matched links was based on the values, not the keys, in order to display the correct casing. Thus the presentation was tweaked to not show the new prefix.

A good test case here is to add this line in Sandcastle's editor and double-click it:

//contains

In the resulting list, Queue.contains is non-static, and Rectangle.contains is static. Both links should work and scroll correctly.

Looks good. Thanks @emackey!
