streams: Add ConcatenatedStream>>#species for a gst-convert fix

gst-convert will construct a ConcatenatedStream when multiple input
files are passed. In contrast to a FileStream the species was Array
and not String leading to an issue with the RBScanner>>#scanNumber.

Add ConcatenatedStream>>#species to return the species of the current
stream.

	* kernel/StreamOps.st: Override the >>#species selector.
	* tests/streams.st: Add testcase.
	* tests/streams.ok: Update the result.
stinst: Make RBScanner>>#scanNumber work for the ConcatenatedStream

The species of the ConcatenatedStream is Array so we will need to
convert the result of reading from the stream with >>#next: to a
String first before we can trim the separators.

	* RBParser.st: Change RBScanner>>#scanNumber to convert
	the result to a String.
	* RewriteTests.st: Add testcase for RBScanner>>#scanNumber.
	* package.xml: Add the new test to the testsuite.
stinst: Fix parsing and formatting of numbers like '(16r02)'

Code like '(Delay forSeconds: 3) wait' got re-formatted to
'(Delay forSeconds: 3)) wait'. The code that extracts the
sourcecode for the NumberLiteralToken should have operated on
the result of >>#previousStepPosition but instead the current
position of stream was used as an end.

Keep the current position of stream as old position, use the
self previousStepPosition to find the end of the number literal,
remove unused variables and remove the trimSeparators as we
are now using the right place to stop.
