Set lt version upper limit to 1.0

[Calum]

For libtorrent 1.1 there are many methods removed for settings etc. that will result in Deluge 1.3 crashing. We will not be adding support for it to 1.3.x series as the changes required are non-trivial.

So the maximum version for libtorrent needs to be set to 1.0.x.

Maybe we should consider doing a 1.4.0 release soonish? Do we have a list of current blockers? Is libtorrent 1.1 support one of them?

I hadn't got around to adding lt 1.1 support ticket to 2.0 roadmap but setting it to 1.1 as minimum was going to be the next task anyway. Also still working towards that release with all those tickets needing completed.

I've tried to look at libtorrent 1.1, but I it segfaults when loading torrents. Not sure if it's the python bindings or something else.

Fixed in 1.3-stable: [852b51f224]
