Thaana romanisation

Currently we are using romanised form of Thaana letters instead of using actual Unicode Thaana letters. This makes things a lot easier for us. The translated romanised output from English to Dhivehi can be converted to Unicode by a simple mapping. This mapping is as follows:

h	<char-0x0780> "letter haa
S	<char-0x0781> "shaviani
n	<char-0x0782> "noonu
r	<char-0x0783> "raa
b	<char-0x0784> "baa
L	<char-0x0785> "lhaviani
k	<char-0x0786> "kaafu
w	<char-0x0787> "alifu  
v	<char-0x0788> "vaavu
m	<char-0x0789> "meemu

d	<char-0x078B> "dhaalu
t	<char-0x078C> "thaa
l	<char-0x078D> "laamu
g	<char-0x078E> "gaafu

c	<char-0x0797> "chaviani

Thaana is written in right to left. however, for romanisation, we use from left to right. so ->

"I am a fisherman"

outputs:

"waharenqnakI masqveriwewq" (read from left to right)

which is

"އަހަރެންނަކީ މަސްވެރިއެއް" (read from _right_ to left)
