Feature Request: Add field to manually specify account expiration date

[doomlord289]

I know CCP removed the ability to query an account's Omega expiration date when they moved everything to ESI, but it would be nice to be able to manually specify the date and time our Omega expires in Evemon.

It would also be nice to be able to highlight the expiration date while viewing a skill plan using some marker similar to the remapping points.

I use the label field to add the Omega expiration date. Highlighting it in the skill plan would be useful though.
