Troll phonology correction

I messed that up. The letters H, W and Y are not used; I and V function as
semivowels as well as vowels. The alphabetical order here is one of
three(another is A C I L M N P S T V).

A = [a]/[@]; [h]/[?] before vowels
I = [i]/[e]; [j] before vowels
V = [u]/[o]; [w] before vowels
C = [k]/[g]
S = [s]/[z]; [S]/[Z] before I
T = [t]/[d]
N = [n]; [N] before C and word-finally
P = [p]/[b]
M = [m]
L = [l]/[r]

Ten letters total: three vowels, seven consonants.
