Title: fix: Allow field.trend YES on fields with a longer name than 15

When configuring trends for a "df"-graph I noticed, that the name of the data source was mangled and thus rrd complained about an "invalid rpn expression".

This commit uses the function "get_field_name" to mangle the name if necessary.
