CB-8750 [wp8]: Allow resolution-specific splashscreen images

Browse Source 
There are two aspect ratios for Windows Phone devices: 15:9 and 16:9. At
the moment, though, there is only one splash screen by default for WP8
Cordova apps. When stretched to fit all possible resolutions, this can
sometimes look bad.

WP supports resolution-specific splashscreens, so this commit adds the
same support to the splashscreen plugin. It uses the same base name for
the splashscreen, but adds modifiers such as ".screen-<res>" based on
the device. If a screen-specific image is found, it is used. If not, we
fall back to the single default image.

Fixes https://issues.apache.org/jira/browse/CB-8750
