Changes JsonDeserializer to use ListBuffer for arrays and objects. Fixes #1487

Using a mutable.ListBuffer to deserialize large arrays and objects provides much
better performance than the existing implementation using List.
Appending to an immutable List is a linear-time operation making the
deserialization of a JSON array an O(n^2) operation.  ListBuffer offers
constant-time append and constant-time export to an immutable List,
bringing JSON object deserialization down to linear time.

Performance tests are also provided.  This test deserizalizes a 2^13
element object 100 times and a 2^16 element array 100 times.

Re-factored build.scala to build.sbt thereby leveraging the new 0.13 syntax. This has the following-on effect of being able to dispense with Play's own Project object for use in sbt build files - i.e. Play now uses sbt in a idiomatic way.

Also, changes to the console that fix up jline upsetting some terminals and the play logo no longer having an exclamation mark (not part of the official logo anymore).
