fix($location): add semicolon to whitelist of delimiters to unencode

Some servers require characters within path segments to contain semicolons,
such as `/;jsessionid=foo` in order to work correctly. RFC-3986 includes
semicolons as acceptable sub-delimiters inside of path and query, but $location
currently encodes semicolons. This can cause an infinite digest to occur since $location
is comparing the internal semicolon-encoded url with the semicolon-unencoded url returned
from window.location.href, causing Angular to believe the url is changing with each digest
loop.

This fix adds ";" to the list of characters to unencode after encoding queries or path segments.
