automatic translation update
refs #1700 time tracking

 * bug fix: min/max generation time didn't work in nested data tables because the column aggregation operations were not passed to sub tables
 * ui improvement: very small values were shown as 0s. use three decimal places if value is smaller than 10ms (e.g. display 2ms as 0.002s instead of 0s)
data table JS bugfix

after changing an option in the cog-menu (exclude low pop or flatten), the number of rows in the report changes. JS used to pass a totalRows parameter to the server that prevented it from recalculating the number of rows. fix: when an option in the cog-menu is changed, delete the totalRows parameter so that PHP counts the number of rows.
