Move hunspell dictionaris out of "third_party/hunspell"....

third_party/hunspell128/dictionaries/README_en_GB.txt

-This dictionary was initially based on a subset of the 
-original English wordlist created by Kevin Atkinson for 
-Pspell and  Aspell and thus is covered by his original 
-LGPL licence. 
-
-It has been extensively updated by David Bartlett, Brian Kelk
-and Andrew Brown:
-- numerous Americanism have been removed
-- numerous American spellings have been corrected
-- missing words have been added
-- many errors have been corrected
-- compound hyphenated words have been added where appropriate
-
-Valuable inputs to this process were received from many other 
-people - far too numerous to name. Serious thanks to you all
-for your greatly appreciated help.
-
-This word list is intended to be a good representation of
-current modern British English and thus it should be a good 
-basis for Commonwealth English in most countries of the world 
-outside North America.
-
-The affix file has been created completely from scratch
-by David Bartlett and Andrew Brown, based on the published 
-rules for MySpell and is also provided under the LGPL.
-
-In creating the affix rules an attempt has been made to 
-reproduce the most general rules for English word
-formation, rather than merely use it as a means to
-compress the size of the dictionary. It is hoped that this
-will facilitate future localisation to other variants of
-English.
-
-Please let David Bartlett <dwb@openoffice.org> know of any 
-errors that you find.
