Add latest version info to reporting

[bergmark]

E.g. I got this output when trying to re-enable tasty

tasty-1.4.1 ([changelog](http://hackage.haskell.org/package/tasty-1.4.1/changelog)) [...] is out of bounds for:
[...]
- [ ] tasty-ant-xml-1.1.7 (>=0.10 && < 1.4). [...]. Used by: library

this lead me to believe that i needed to disable tasty-ant-xml, but there was an upper bound on it that can be removed instead.

Would help if the output was something like

tasty-1.4.1 ([changelog](http://hackage.haskell.org/package/tasty-1.4.1/changelog)) [...] is out of bounds for:
[...]
- [ ] tasty-ant-xml-1.1.7 (>=0.10 && < 1.4). [...]. Used by: library (Later version available: 1.1.8)

Perhaps obsoleted somewhat by commenter now?
