DECODR1611

Added a event log UTC to PST utility - CalCOFI 1611SR CTD data acquisition computer and bridge event tablet (and all shipboard computers) were set to UTC. The PST column in CESL and CELog were computer time ie UTC so -8hrs needed to be subtracted from the UTC event times. DECODR's "Clean Event Log" button checks the PST vs UTC and if they are the same, it subtracts -8hrs from the PST date/time.

Under the CSV tab, there is also an interactive utility that lets the user correct StartCast, AtDepth, EndCast dates-times in the casts.csv by adding or subtracting 8hrs.

Tweak: "Cruise Ave" O2s are selected by default in the [ CTD BTL to Sta.csv ] module since they are preferred over "Sta Corr" CTD O2s.
