Several Changes (options, refactoring, and bugfixes)

[Erotemic]

Change 1: Moves formatting code into its own module.

Change 2: Adds an argument options to static_init. Currently there are 3 options available:

• with_attrs: Allows you to enable/disable exporting internal module attributes
• with_mods: Allows you to enable/disable exporting modules themselves. This addresses point 3 in __all__ generation? (and other things) #1.
• with_all: Enable/disable generation of an __all__ variable. This addresses point 5 in __all__ generation? (and other things) #1.
• relatives: * If True generates code with relative instead of explicit imports. This addresses point 4 in __all__ generation? (and other things) #1.

Change 3: Improved algo for selecting where to insert auto generated text when AUTOGEN_INIT tags are not give. This changes uses the xdoctest PS1 parsing logic to determine if a line is "top-level". This prevents clobbering of some multiline statements. Current solution should be refactored and improved, but its much better than the old algo.

Change 3: Removed attr kwarg from static_init, use options['with_attrs'] instead. This is a breaking change.
