vzctl set --features: ability to specify a few features at once

In fact, there already was an ability to specify a few features
at once, like this:

	vzctl set NNN --features "one:on two:off" --save

It is a bit inconvenient to quote the argument. After this patch,
one can use:

	vzctl set NNN --features one:on,two:off --save

Features are still saved to config file in an old way, ie space-separated.
