MAJOR: Node Screens display better pricing info.

• Nodes now show the true price on node Displays when affected by specials/multipliers/etc
• Previously, specials costs/etc weren’t being displayed on the node.

Timeblocks: add new option 'sell_timeblocks_kiosk'

• if enabled, kiosks will allow sale of timeblocks
• if disabled, kiosks will not allow sale of timeblocks (but will still display timeblocks previously on cards)
• the idea here is, you can enable timeblocks everywhere else (on arcade machine nodes, and on cashier page), while leaving the kiosk normal
• for using these with scenarios like admins handing out cards with timeblocks preloaded on them (i.e. for special groups/parties), but, not wanting to let players buy them on kiosks directly

Internals:

• allow customer access to the Rfpay web console (ask us if you're interested)
• kiosks: allow auto-creation of kiosks on first use
• cleanup some kiosk UI issues when displaying player timeblocks and points balances together
• re-add “upload graphics” button for individual nodes
• font flash screen no longer shows the font test
• many more small fixes/tweaks/UI improvements
