• Another memory issue

Found when monitoring Chatty's PID with TOP, while performing several tasks like:

• Launching dialogs and entering conversations increased the RAM usage; when closing the dialogs or returning to the main-view again, the RAM usage decreased almost to the initial value.

• When opening a couple of conversations, which have been active once but removed from the conversations list, the memory usage increases notably due to the loading of the chat history. But when leaving (not deleting) the conversations, the memory usage remains almost the same. Since the tabs/view closes when leaving a chat, the mem for the chat history seemingly wasn't freed. Seems to be related to chatty_conv_delete_message_history().
