Subject: Fixed bug in RST reader:  previously, code blocks had to be indented
 a full tabstop, but RST allows any amount of indentation. Resolves Issue #27.

+ removed 'variable' parameter from indentedBlock function in
  RST reader, as it is no longer needed
+ updated test suite
+ updated changelog
