start recording from TSmax+10000
added TS-offset field

and some more tooltips
default target is 'usage'
it's 'make <PYFILE>'
Merge branch 'master' of github.com:iem-projects/WILMAmix
added /record/timestamp/offset
settable record-offset
apply record-offset from settings when co-launching
regenerated GUI
it's "recordoffset" not "offset"
maximum ts-offset is 1000 kSamps
ts-offset is in kilo-samples
check whether the ts-array is non-empty

if there are no selected SMi's, there are no timestamps...
convert ts-offset to kSamples (and check errors)
apply ts-offset to MIXconfig
regenerated MIXconfig gui
all args on single-line

(so we can more easily disable them)
