Subject: this patch introduces a new command script import command which takes
 as input a filename for a Python script and imports the module contained in
 that file. the containing directory is added to the Python path such that
 dependencies are honored. also, the module may contain an
 __lldb_init_module(debugger,dict) function, which gets called after
 importing, and which can somehow initialize the module's interaction with
 lldb
