Added code to set up the marketplace session cookie and use it for subsequent posts and gets to the inventory import API

The mouse position is checked every frame in relation to the toast to catch the mouse leaving the toast "i" button when the toast is moved by the screen channel.

The fix is intended to avoid the toasts that don't fade in the following scenario:
1. Have User A Send 4 IM messages to User B: a, b, c, d
2. Have User B hover their mouse over the i on toast c (don't click on it just hover)
3. As the other toasts fade observe toast c moves up to the top and does not fade

Minimum window size setting no longer forces propagation to the OS before root view is initialized.

EXP-1451 FIX -- I want to put my NEARBY CHAT window at the bottom left, but then it obscures chatted text.

I repositioned the chat, move and camera floaters.  Chat toasts now start 80 up from the bottom left rather than 10.

EXP-1649 FIX +1 (client) Turn off web loading spinner until a more visually pleasing one can be defined

EXP-1476 FIXED (Moving speak button to empty toolbar while incoming/outgoing call dialog is open does not move the dialog as well)
Reason:
A floater can be docked only to a button which is in visible chain, the visibility of the button itself is not enough.
After the button was added to the empty toolbar: mButtonAddSignal is called and the floater tries to dock to the button, but the button's parent(mButtonPanel) is yet invisible at this moment (so the button is not in visible chain). mButtonPanel visibility updates in draw() depending on whether it contains some buttons or not.

Solution:
Updating mButtonPanel visibility right after the button was added, before mButtonAddSignal
