Font styles do not work on macOS

[achabotl]

Italic and bold fonts are no found on macOS. The cause is a case-sensitive check that the filename contains the string italic or bold. Fix incoming.

enable/kiva/fonttools/font_manager.py

Line 557 in 6cf525c

if sfnt4.find('oblique') >= 0:

Here's a minimal example with the broken code.

from kiva.fonttools import Font
from kiva.image import GraphicsContext
from kiva.constants import ITALIC, BOLD

gc = GraphicsContext((200, 200))

gc.set_font(Font('', size=24))
gc.set_text_position(30, 120)
gc.show_text("Hello World")

gc.set_font(Font('Georgia', size=24))
gc.set_text_position(30, 80)
gc.show_text("Hello World")

gc.set_font(Font('Georgia', size=24, style=ITALIC))
gc.set_text_position(30, 40)
gc.show_text("Hello World")


gc.save('text.png')

I think this may be a duplicate of #391.

Yes, it's same root cause.
