Fix of data error in 2_S_RECC_FinalProducts_2015_passvehicles (+ single EU country data added)

[chauenstein]

2_S_RECC_FinalProducts_2015_passvehicles_V1.3 (and previous versions) included a wrong fuel type split of the historic vehicle stock for EU countries and regions (due to a bug in the R script used to generate the data).
In 2_S_RECC_FinalProducts_2015_passvehicles_V1.4 this is corrected.

Additionally, historic stock values for previously not included single EU countries is added (Classification for regions unchanged; grouped EU regions 'R32EU12-M', 'Oth_R32EU15', and 'Oth_R32EU12-H' unchanged regarding the countries include, however, values updated to correct data error from previous verisons).
