Only one styled window on restarting atom

[c-vetter]

Only the first window gets user styles when atom is restarted with multiple windows.

Reproduction Steps:

1. Change theme settings to Purple, with custom colors
2. Open multiple windows
3. Exit and re-start atom

Expected behavior:

All windows should have the custom styles all the time

Observed behavior:

All new windows get the custom styles during step 2. After step 3, only one window has the custom styles.

This is fixed in Material UI 2.0 (available for Atom 1.17-beta). Upon restarting Atom all opened windows get the latest color (and all windows update the colors when changing from one)
