gimp_gimprc_set - Sets a gimprc token to a value and saves it in the gimprc.
SYNOPSIS
gimp_gimprc_set (token,value)
DESCRIPTION
This procedure is used to add or change additional information in the gimprc file that is considered extraneous to the operation of the GIMP. Plug-ins that need configuration information can use this function to store it, and gimp_gimprc_query to retrieve it. This will accept _only_ parameters in the format of (<token> ), where and must be strings. Entries not corresponding to this format will be eaten and no action will be performed. If the gimprc can not be written for whatever reason, gimp will complain loudly and the old gimprc will be saved in gimprc.old.
