Project.py: Ask to select languages

[ishanSrt]

• The interactive mode of coala-quickstart now asks to select languages too.
• The green_mode of coala-quickstart also asks to select languages by default. This behaviour can be overridden by the use of the non_interactive tag.
• Two new arguments are introduced max_args and max_values to be used along side the green_mode to specify the maximum amount of optional settings for the bears to test against and the maximum values that can be guessed against each optional setting respectively.
• Other minor changes include refactoring of some variables from global to local scope and addition of tests.
