Problem to solve

Expand the ability of developers to select or create theme.themes object colors within the vuetify plugin having an opacity element to them (e.g. #000000de). At present, theme colors are limited to the six digit variety.

Several colors in use by vuetify itself (such as text colors) make use of the opacity digits, but the theme engine does not. This would add parity to that situation.

Proposed solution

Modify the underlying source code to handle all eight hex color digits correctly.
