Title: Fix #552 Compensate for JLine's absent EOF detection.

In the unsupported terminal mode, JLine treats a broken
stdin as an endless stream of empty lines. This is problematic
for idea-sbt-plugin: if the IntelliJ process is forcibly killed
and leaves the child SBT process running, it consumes considerable
CPU processing these.

Patching JLine itself would be the cleanest solution (the change
has already been applied to JLine 2), but I've shied away from that
and instead wrapped the InputStream that is read by JLine to
intercept the result of -1 from read(). When this happens, the
flat `inputEof` is set to true.
