support path parameters in WAUrl

[GoogleCodeExporter]

There is a really rarely used syntax in URLs that allows adding path parameters 
to each path element [1] [2]. Resulting URLs may look like this:

/path/name;param=val1,val2,val3
/path;param1=val1/name;param2=val2

Many Java web servers use this for session tracking (session key does not have 
to be repeated in forms). The reason this is interesting for us is that some 
affinity aware load balancers therefore expect sessions ids to be passed like 
this instead of query parameters. This issue is just about adding support for 
support path parameters to WAUrl, nothing in the current session tracking 
should be changed

Since this hasn't been used in ten years the implementation should take care 
that when not needed the cost of this feature is a just nil field in WAUrl.

The code is a bit ugly. Care has been taken that the pathParameters instance 
variable stays nil unless there actually are pathParameters. The parsing 
overhead if there are no path parameters is an additional #indexOf: (which is a 
primitive) for each path element and an integer counter. The path parameter 
parsing code makes a few to many copies but that shouldn't matter since I 
expect at most one path element.
