Detailed Description

Helper class to keep track of what we're currently rendering and in what order Some constraints that may not be obvious

Rendered views are not always contiguous. When we clear the chatlog ongoing file transfers are not removed or else we would have no way to stop them. If history is loaded after this point then we could actually be inserting elements both before and in the middle of our existing rendered items
We need to be able to go from ChatLogIdx to rendered row index. E.g. if an SQL query is made for search, we need to map the result back to the displayed row to send it
We need to be able to map rows back to ChatLogIdx in order to decide where to insert newly added messages
Not all rendered lines will have an associated ChatLogIdx, date lines for example are not clearly at any ChatLogIdx
Need to track date messages to ensure that if messages are inserted above the current position the date line is moved appropriately

The class is designed to be used like a vector over the currently rendered items, but with some tweaks for ensuring items tied to the current view are moved correctly (selection indexes, removal of associated date lines, mappings of ChatLogIdx -> ChatLine::Ptr, etc.)
