Change loading screens to be more descriptive

When transferring, the loasing screen seems to start at the highest number until it actually starts transferring. (i.e., 250/250, then jumps to 0/250 and starts counting up)

Should try to adjust this so at first it says "Initializing mint engine..." or something related to what's actually being done in the background.

hard setting a generic message before running transfer/mint would solve this and #74

I may do this in php right after the user clicks the button

New function prints a generic "Initializing" message for each component
