Final fix for #290

[pushrax]

Works for Go 1.3+ only, should we increase the minimum Go version for Revel?

[brendensoares]

@pushrax that's a good question. Here's a dumb question in return: Where do we declare a minimum Go version for Revel?

As a temporary fix, could we include the -i flag dynamically based on the current version of Go?

@brendensoares, as I know .travis.yml is the only place where Golang version is defined. There is a special // +build constraint in Golang, but Revel doesn't use it.

[brendensoares]

@AnonX // +build "go1.3"?

[brendensoares]

@robfig @pushrax it seems -i may not be the solution per the latest developments on #290

Closing this for now since it needs further investigation.
