Cross-build for SBT 1.0.0

[liff]

Mainly to see how/if it works, I guess :)

Uses crossSbtVersions from SBT 0.13.16.

See also: #62.

@jrudolph when you can merge this PR?

[timothyklim]

@jrudolph any chance that this PR will be merged and released?

[jrudolph]

There seems to be some demand, so we'll try to get to this sometime this week.

[ngbinh]

+1 for this! Thanks

[liff]

Updated for 1.0.0-RC2, which seems to allow src/main/scala-sbt-1.0 instead of the full binary version.

[jrudolph]

Thanks, @liff. It basically seems to work for me. It seems that color logging is lost in 1.0.0-RC2, do you have seen this as well? Did the behavior of Logger.ansiCodesSupported change?

[liff]

Didn't notice that, sorry. Looks like in 1.0.0-M6 and RC2 ansiCodesSupported is just false. A regression in SBT perhaps?

[liff]

@jrudolph reported sbt/sbt#3336

[jrudolph]

Thanks, I guess we might just ignore that for now and try to find out if that can be fixed in sbt.

[liff]

Updated. Color logging regression is fixed in 1.0.0-RC3.

[mielientiev]

@jrudolph I believe after @liff fix we can merge it.
What do you think?

[martijnhoekstra]

@jrudolph just in case this escaped your attention and slipped through the cracks, there is hot demand, especially now that 1.0.0 final is out. A merge and release would be most appreciated

[jrudolph]

Thanks for notifying. We were just a bit delayed by summer vacations. We'll make a release asap next week.

[jrudolph]

Thanks a lot, @liff. I tried it locally and it works perfectly.
