Title: Specifying functions to be computed at build time as key values

I feel that sometimes moving all config to `build.scala` just to add build time to BuildInfo can be cumbersome, so in this pull request I added a way to specify BuildInfoKeys as values like this:

```scala
buildInfoKeys ++= Seq[BuildInfoKey]("buildTime" -> (() => System.currentTimeMillis))
```
