Remove Arabic suffixes

Description

Removes some Arabic suffixes from a unicode string. The suffixes (in order of removal) are: "ha-alif", "alif-nun", "alif-ta", "waw-nun", "yah-nun", "yah-heh", "yah-ta marbutta", "heh", "ta marbutta", and "yah." Suffixes are removed from a word (as defined by spaces) only if the remaining stem would not be too short. Only one suffix is removed from each word.

x5 = 4, x6 = 4, x7 = 4, x8 = 3, x9 = 3, x10 = 3, 
dontstem = c('\u0627\u0644\u0644\u0647','u0644\u0644\u0647'))
