MFC INDEX.keymaps fixes
r282898: Correct UTF-8 encoding in Británico
One á was ISO 8859-1 0xE1 instead of UTF-8 0xC3 0xA1.
r282902: Correct language code -- "Danish" is English
The menu entry "Danish ISO-8859-1 (macbook)" was first added to the syscons(4) INDEX.keymaps in r241851 with no language code, and then in r256367 incorrectly tagged with "da". It is a Danish keyboard map, but the description is in English and therefore must be "en". This error subsequently propagated into the vt(4) INDEX.keymaps.
