Interface Updates

• Fix selecting groups from Scatter Plot, it was showing several empty rows before the groups started.

Model Updates

• Added elcaput1, elcaput2 to control the PID process for Capacity Utilization, which is problematic after 2100, for example for VADD(Israel, Materials), changing these parameters to 0 after 50 years helps, combined with changing elinst1 and elinst2 for IDS.
• Change in function: "GDP/Capita (PPP) Versus Cobb-Douglas Alpha (GTAP 5)" shown below.
• 

The original function arrived at 20 when GDPPCP was around 315, and then stayed flat, producing transients in GDP growth, so we have now slowed down the reduction of Alpha by changing the coefficient of the slope from -0.1 to -0.05, which gives us more time before reaching limit levels, which have also been relaxed from 20, down to 5.

Also a limit on VADD was found that affected the US, Services in the SSP5 scenario, the limit has been increased by a factor of 10.
