Do not count long poll connections against CurlConcurrentConnectionsPerService

This is necessary for opensim mega regions that can have up to 16 long
poll connections for a single service, while upping the maximum number
of connections per service just for that is clearly nonsense.

I also changed that long poll connections do not "use" the "Other"
capability type (which shows that the debug info in the HTTP debug
console for the Other capability type turns grey when it only has event
poll connections). As a result additional connections become available
for textures, mesh and the inventory (the other capability types) on
opensim, which has all types on the same service, because now Other
does no longer constantly reserves a full share of the available
connections. This makes the actual number of connections used for
textures and mesh a lot more like it is on Second Life.

Feature Request: Allow typing login uris into the grids combo box on the login screen

Furthermore, users may now type in grid name, grid nick, or grid login uri into the box and it will resolve to an existing grid they've used before, or (for uris only) try to add the new grid with the data it provides.
Input will have trailing and leading spaces trimmed.

Thanks to Diva Canto for this brilliant request!
