3.0 branch, updated nuspec files

[12:04:49 AM] Ben H: i think we should move to MVC5 + Razor3 in the next release
[12:04:55 AM] Dejan Miličić: I agree
[12:04:56 AM] Ben H: that means .NET 4.5 minimum
[12:05:01 AM] Ben H: no more Server 2003
[12:05:23 AM] Ben H: I guess the next version should be 3.0 as well, since it is a breaking change we should increment the major version
[12:05:39 AM] Ben H: I'm heading to sleep but can you discuss with Cristian if you see him online?
[12:05:46 AM] Dejan Miličić: yes, will do
[12:05:54 AM] Ben H: thanks
[12:05:56 AM] Dejan Miličić: so we could have 2.6 soon
[12:06:14 AM] Ben H: let's just have 3.0
[12:06:29 AM] Ben H: I tried upgrading one of my sites to 2.6 and it was all messed up because of partial .NET version upgrades
