Added methods for getting a frame's current font and

for calculating the nsIFormControlFrame's NavQuirks size
Added two methods for getting the "wrap" property and andded a new enum
for for testing against instead of a string
Added a method for calculating the size when in NavQuirks modes, this currently
duplicates the algorithms for for input text and textareas
