Keyword syntax hightlighting on ImportTool methods

[hkailahi]

Current syntax highlighting:

import somelib
import otherlib
from blah import thing1, thing2

from bd.import_tool import ImportTool
ImportTool(locals_dict=locals())\
.from_( "foo" ).import_( "a" )\
.from_( "bar" ).import_( ["x", "y"] )\
.from_( "baz" ).import_( "f" )\
.from_( "baz" ).import_( "e" ).as_("🔥🔥🔥")\
               .import_( "g" ).as_("e")\
.import_( "qux").as_( "yeezy" )\
.import_( "new.dis.who.🍌" )

To better get the point of this library across, provide the same syntax highlighting for from_, import_, as_, and any ImportTool.{*} as corresponding python keywords (from, import, as, ...).

Check out Linguist (Github syntax highlight configurations). Maybe as simple as setting linguist-language in .gitattributes to our own forked variation of MagicPython???

# Example of a `.gitattributes` file which reclassifies `.py` files as `pYtHoN`:
*.py linguist-language=pYtHoN
