Correct progress reporting in Pointwise plugin

This commit adds the appropriate code to more accurately report the
progress of the vertex export in the SU2 Pointwise plugin.
Guarantee DV_KIND comes before DV_PARAM in options

This makes sure DV_KIND comes before DV_PARAM when a config file is
output by the python scripts. The python dict passed to update doesn't
guarantee order. This issue occured when DV_KIND and DV_PARAM
were not previously defined in a config file passed to
shape_optimization.py
Added descriptions to variables that lacked them, and change 1d_Output to One_d_output
 there is no restart file messages only output on master node
