Show “loading” indicator whenever a process takes longer than a split-second

This feature is covered in the "Multi-threading" feature added to the current DEV release. It will be pushed within the next BETA release (coming soon). With the multi-threading feature, users will see "loading" indicators after clicking a button where the action takes more than 0.5s, and we will mutli-task actions (such as SEND, RECEIVE, CONVERT, BUY, etc). The multi-tasking actions may be viewed by clicking on the "bell" icon (in the next release). The "bell" icon will also "ring" animate whenever it is "working on something."
