added project generator icons for web2py and flask
initial 2-step create new project dialog in PyCharm
added logos for twitter bootstrap and boilerplate.
Use renamed getIcon to getLogo to not mess with IDEA project creation
moved getSettingsPanel and getSettings from DirectoryProjectGenerator to PythonProjectGenerator. We don't push other projects to change new project dialog.
extracted template folder creation into TemplatesService and reused in different python project types
moved flask plugin to pycharm ultimate repository.

Since we have a community edition there is no point to have it in contrib repository.
