Reading trends from RRD in Lua

[Domoticatorino]

Hi, great job.

in you script you wrote:

name, csv = trend_export(name, dates, 'csv', 'unixepoch')

but I think you should complete as follow:

name, data, csv = trend_export(name, dates, 'csv', 'unixepoch').

In this way I received the file by mail. GREAT.

But unfortunatey time stamp is not human readable.
