Set pixels brightness; recall display brightness setting in auto dim mode

[CedarGroveStudios]

1. Add the capability to set pixel brightness when instantiating PyBadger. Use the standard value range for NeoPixels. If omitted, default to brightness value of 1.0. Example:

from adafruit_pybadger import PyBadger
pybadger = PyBadger(pixels_brightness=0.01)

2. Use setter value rather than brightness=1.0 when restoring to initial brightness with auto_dim_display():

pybadger.brightness = 0.9  # set initial display brightness

Travis errors are completely Greek to me. I'll need some help with this one.

Ah, that's an easy one. As it suggests, add 12 spaces to the left of that statement. :)

Thanks! Where can I find the Travis details (asked the newbie)?

[makermelissa]

On the checks tab.

Thanks @makermelissa. The browser app's checks tab didn't have that level of detail. Saw that pylint can be used to reveal the details. May be time to switch to Linux.

This appears to be a value for display brightness. Can we name it something like _display_brightness so it doesn't get confused with neopixel brightness? It makes reading the code a bit easier. Thanks

[CedarGroveStudios]

Excellent idea. I'll make the change.

Sorry, I meant under the Checks tab, you need to click the link labeled "The Build" and it should get you there.

Looks great! Thanks
