New info, warning, danger colors

Created by: rrhyne

To implement notices and alerts, we needed to add a 4th color value to each of the semantic colors:

primary-04 / Light - #E1F0FF
success-04 / Light - #EBFAEE
info-04 / Light - #EAFAFC
warning-04 / Light  - #FFF7E1
danger-04 / Light - #FBEAEA
secondary-04 / Light - #F1F4F9
merged-04 / Light - #EEE9FD

primary-04 / Dark - #03284F
success-04 / Dark - #054410
info-04 / Dark- #025762
warning-04 / Dark   - #3D2904
danger-04 / Dark  - #3D0A0A
secondary-04 / Dark  - #545967
merged-04 / Dark  - #1F0A5C

Additionally a 2nd link color was required to ensure the blue links have accessible contrast on notices:

link-color-2 / Light - #0766CC
link-color-2 / Dark - #70B0F3
