Before this commit, cids in the url (in the hash part) were separated by a comma, which was encoded by encodeURIComponent as it is not considered as a safe character, resulting into "%2C" appearing in the url in between company ids. This was kind of ugly and made the url a bit hard to read. This commit uses "-" as separator for cids, which is a safe characters [1] to use in the url and which is thus left untouched by encodeURIComponent. AL request.
