[Kde-pim] Supported Compilers / C++11 Support in KF5

[Andrius da Costa Ribas]

I'm experimenting with intel compiler on windows, but those four features
are documented as supported[1] from version 14.0 on (never tested those
features, though), so it looks like it won't be a problem here either.

cheers,
Andrius.
