Web.BaseURL without trailing /

[edA-qa]

The system tends to behave differently when Web.BaseURL has a trailing / or not. The gotoRelativeURL function has fixed this in the one case, but the fix needs to be general. Also the Java URI class has a defect in this regards, so functions like combineCurrentURL need to be patched to address it (see gotoURL in WebTestUnit).

Essentially, for all combinations of this domain:

http://domain.com
http://domain.com/

And these paths

index.html
/index.html

Combining these yields the same URL in all cases.

I modified combineURL and made WebTestUnit call this, as well as CreateHTTP server, nowhere else used Web.BaseURL.
