Add message details menu button

[esensar]

Adds a "Properties" menu button in conversation, when one message is selected, which displays details about the message:

• Type (SMS or MMS)
• Sender phone number (or receiver if it is a sent message)
• Used SIM
• Date sent at
• Date received at (if it is an incoming message)

This closes #19

TODO

• [x] Wait for https://github.com/SimpleMobileTools/Simple-Commons/pull/1733 to be merged and update Simple-Commons ref

I am not sure if we need to keep track of date_sent everywhere, since for now I have decided to keep it the same as date in case of sent messages and only update it in case of incoming messages. I have noticed that Google's Messages application has the same behavior (only displaying received time if it is an incoming message).

When it comes to sender/receiver phone number, I only display the number of the other participant, since getting the phone number of used SIM does not seem to have a reliable solution (even Google's Messages requires user to enter their phone number to display it in details).

Sent at doesnt seem to work, it always shows 1.1.1970 to me. By showing sent/received I meant always showing 1 only. At messages that we sent, we show "Sent at", at messages that we received we show "Received at". Never both. Remove the message type, doesnt make sense showing SMS/MMS there. Also redesign the dialog, make it look like file properties with a label and value. And at Sender lets show the contacts name (if we have it) with the number after it in brackets.

as Sent at doesnt work, guess we can use the received value or whatever other date we have at the messages we sent too, to show a reasonable date when we sent the message.

I think what we have currently should work fine, I think I broke it in attempt to enable showing both "Sent at" and "Received at", since I thought that was the goal (I noticed some other apps supported that).

I will remove that and it should make everything much more simple.

alright thanks, seems to work well to me
