Add Wiki-Solar data contributions.

Wiki-Solar (https://wiki-solar.org) has graciously agreed to a data
sharing arrangement which included making substantial contributions to
fill in geographies where data was severely missing in the Global Power
Plant Database. This addition adds over 3700 solar facilites totalling
over 113 GW of capacity to the GPPD. It adds the first solar plants for
46 countries, including the first power plants of any kind for 3 countries.

Includes first power plants for:
PSE     Palestine
SUR     Suriname
LCA     Saint Lucia

Gains over a GW:
CHN     China (~52GW = 17x increase)
IND     India (~23GW = 9x increase)
JPN     Japan
CHL     Chile
AUS     Australia
DEU     Germany
ESP     Spain
MEX     Mexico
BRA     Brazil
VNM     Vietnam
ITA     Italy
FRA     France
OMN     Oman

For the present the USA is excluded from the list provided by Wiki-Solar,
since those facilities are expected to be made available through the US EIA.

Net change of +3733 plants @ 113.34 GW.
