New features:
- add support for python2. You may now use python2 for writing a pyqode
app (backend AND frontend)!
- make use of the new modes introduced in pyqode.core (occurrences
highlighter, extended selection, global checker panel,...)
- automatically fold docstring when opening a document
- many improvements to the auto indent mode. It is more robust and should
resists malformed code (e.g. unclosed parentheses,...)
Fixed bugs:
- fix cursor position after unindent
- fix a few bugs with autoindent
- fix pyinteractive console colors on dark color schemes
