Show conversation stats per organisation

[dkhgh]

I was wondering if it would be interesting to add stats about the amount of conversations per organisation (in total or per year/month/week/day).

Plus a general stat of # of conversations a day would be nice.

#75 is nice btw

Currently showing the total number of conversations per company within the selected time frame. An overall number conversations could be useful, but a lot of clients stay in the conversation for multiple issues though.
