Moves many methods previously provided by implicit conversions directly onto the classes
for better discoverability, especially with scaladoc.
1. Initialize now allowed in more places. Minor renamings in Initialize to avoid conflicts
a. map -> apply
b. get -> evaluate
2. Identity on Scoped* is deprecated- it is now redundant
3. Can now use += and <+= for String, Int, Long, Double settings.
There may be some problematic corner cases in inference, especially with +=, ++, <+=, <++=
4. Some classes with a scoped: ScopedKey[T] method now have scopedKey: ScopedKey[T] instead.
5. The implicit conversion to ScopedKey[T] is now deprecated. Use the scopedKey method.
6. :== and ::= are now private[sbt] to better reflect that they were internal use only.
- drop fillThis: handle in injectStreams instead
- simplify InputParser construction (at the expense of implementation simplicity)
- split out ScopeKey/initialization parts of Setting with separate Initialize trait
+ makes Apply obsolete
+ makes the Initialize trait properly composable
+ this allowed splitting the InputParser definition into
an Initialize for parsing and one for the action
- implement test-only
- inject resolved scope
first phase resolves referenced build URIs as each build is loaded
second phase resolves references without an explicit project ID
(this requires the whole structure to be known and this isn't available during the first phase)
setting resolution is unchanged (done after both phases)
finish alias support
better project printing in 'projects'
completion support for 'help'
resolve URIs in ProjectRef against base URI of defining build in keys and project relations
resolve base directories and record build URI in BuildUnit
preserve relative paths in File to URI conversion for later resolution
