Title: Bug 33 Coal imports incorrectly calculated when supply of solid fuels is greater than demand

Content: If you set the calculator to supply more bioenergy than is used e.g.:

http://2050-calculator-tool.decc.gov.uk/pathways/10b1n211112111110344124004414440314404203304440420111/sankey

Then the value of vector Y.04 Coal oversupply (imports) is set incorrectly. 

The cause is sheet XVI.a row 61. It has no impact on greenhouse gas emissions. But it does impact on the primary energy chart and (possibly?) energy security calculations.

Then the value of vector Y.04 Coal oversupply (imports)  includes that oversupply, where it perhaps should have ended up in the Y.01 Biomass oversupply (imports) vector.

The emissions sequestered by growing the biomass are also counted, even though the biomass is available for export. It is not clear whether or not this is the right thing to do, given that bioenergy imports are counted as zero emissions.
