[whatwg] HTML5 typos

[Kartikaya Gupta]

I ran the spec through a typo-finder program I cooked up and it found these among lots of false positives.

altogther (4.8.2.1.13)
approprate (5.8.4)
argments (4.8.11.1.10)
asychronously (5.8.4)
attribue's (2 in 4.6.12)
attrbutes (4.10.4)
constaints (4.10.14.2, 2 in 4.10.14.3)
elemnt (4.10.14.3)
elment (6.5, 4.3.1)
follwed (4.10.2)
fouth (4.10.9)
implementaion (5.7.2)
indicies (4.10.1, 4.10.6)
knowns (4.2.2)
oherwise (3.3.3.5)
snipet (4.6.10)
sebsteps (5.8.4)

Also, the following words appear with different spelling variations; I suggest one of the variants be picked and used consistently:

behaviour vs. behavior
favorite vs. favourite
honour vs. honor
occurance[s] vs. occurrence[s]
categoris* vs. categoriz*
recognis* vs. recogniz*
serialis* vs. serializ*
tokenis* vs. tokeniz*
