List view of all tasks for a GHOP student. Link 'List my tasks' in the GHOP program submenu is now active for a GHOP student and displays all tasks (grouped by organizations) which the user is involved in.

getListContentForData function added to lists helper. It allows to manually set a list of entities which is to be displayed on the view. Previously, the only function was getListContent, but it retrived data on its own by a single query. The new function can be useful whenever it is impossible or very awkward to obtain entities in such a way (for example more sophisticated SQL statements). Additionally, the getListContent function is reconstructed so that it collects the data first and then calls getListContentForData.

HtmlSanitizer becomes Python 2.6 compatible. The Cleaner class must not have any arguments when calling __init__ function for the object class, because in this case Python 2.6 raises TypeError (while previous versions just ignored them).

Convert gen_app_yaml.py to optparse This allows for example the -f flag to be specified as the second argument. Also add a '-i|--interactive' flag which asks for the application name interactively.
