Per-tab limit on transfers

[Daniel Beardsmore]

Site Manager permits assigning a connection limit to individual saved sites.

Settings permits a global cap on connections.

In order to use multiple servers at once, you need to raise the global cap on connections. When you do that, you remove the connection limit for hosts where it's not specified explicitly.

Ideally, the global limit would be per-host/session (i.e. per tab), not overall, i.e. with a per-session limit of 1 connection, each tab can transfer one file at a time, but every tab is permitted to transfer data, instead of having stalled tabs.

At the moment, a global limit of 10 means that unrestricted/ad-hoc connections will get all 10 connections at once. This means that the limit must be set on every site one by one manually in Site Manager otherwise the global limit doesn't do anything useful, and this seems wrong.

Not a huge issue, just something to play with one day.
