more changes in 0.6

[daanhb]

These were some changes lined up for inclusion in 0.6. I propose we quickly make a 0.6.1 rather than waiting for 0.7.

It is breaking because of changes to intervals:

• the halfline can now be open or closed
• intersection of intervals now takes into account whether they were open or closed

The biggest change I guess is this one. Before:

julia> using DomainSets

julia> (1..2) \ (2..3)
1..2

After:

julia> using DomainSets

julia> (1..2) \ (2..3)
1..2 (closed–open)

I agree, it's fine if v0.6.1 has more breaking changes
