* improving documentation of AndroAuto module

* changed session usage in androlyze: now, a session is always used but you are asked if you want to save it when existing ipython

Yet another patch release!

* Fixing GUI issues

In order to not break existing tools, some functions were re-added in this patch release.

Note that still some functions are renamed or even removed due to
refactoring and reorganization of the parser.
As the method of resolving namespaces has changed, some methods do
not make any sense. Please check your projects!

Some bugfixes and (re-)adding functions:

* Added `is_valid()` to `AXMLPrinter` and `AXMLParser`
* allow packages in app name for example when parsing `framework-res.apk`
* Adding functions to get interfaces, parent class and name on `ClassAnalysis`
