#17 ATTACH constants not parsed

[Tony B]

in 1.2.1
It appears that ATTACH constants did not make it into the parsers (https://wiki.secondlife.com/wiki/LlGetAttached)
I had
ATTACH_HUD_CENTER_2
ATTACH_HUD_TOP_RIGHT
ATTACH_HUD_TOP_CENTER
ATTACH_HUD_TOP_LEFT
ATTACH_HUD_CENTER_1
ATTACH_HUD_BOTTOM_LEFT
ATTACH_HUD_BOTTOM
ATTACH_HUD_BOTTOM_RIGHT

and they were all flagged
