updated regions, buffers. about to try on optimus.

deleted redundant Antarctica shp and csv, since covered now by
sp_*gcs.{shp|csv}. moved buffer csv outputs ({sp|rgn}_[buffer]_data.csv)
from git-annex to ohiprep. updated README. see ohi-science/ohiprep#40
and ohi-science/ohiprep#74. trying on optimus (64-bit GP dedicated Win)
instead of amphitrite (32-bit virtual Win) b/c of memory issues.

last run of fix_land-mid-eez-RUS-SVA-
UK_duplicate-spid-SVA_null-inland1km-offshore1km-CAN.py on amphitrite:
failed to dissolve to sp_[buf]_gcs: sp_offshore1km_gcs
Invalid Topology [Out of memory.]
failed to dissolve to rgn_[buf]_gcs: sp_offshore1km_gcs,
sp_offshore3nm_gcs
Invalid Topology [Topoengine error.]
failed to erase sp_landfix_buf60km: sp_inland50km_gcs
The table was not found. [sp_inland50km_e], Out of memory

TODO: SUM(area_km2) by sp_id (and rgn_id?)
for
G:\ohiprep\Global\NCEAS-Regions_v2014\data\rgn_inland1km_gcs_data.csv
since dissolve doesn't seem to work
