Tip Jar with a target

// CARP Donation box script. Written by Angel Fluffy, with credit to :
// Keknehv Psaltery, jean cook, ama omega, nada epoch, YadNi Monde
// for their work on the "DONATION box" script upon which it was based.

// first line of hover text above box (always constant)

// when total donated this month is less than monthlyneeded, display whatfunding_1 as the funding target,
// when it is more, display whatfunding_2. This allows you to show your donors when you have switched
// from funding your essential running costs to funding expansion.

// The script displays a countdown in SETTEXT above the prim its in, counting down until this target is reached.
// After this target is reached, the countdown disappears, being replaced with a tally.
// The goal of this is to encourage people to donate by setting a clear goal they feel they can help achieve by donating.

// These starting numbers will have the donations the script recieves in between each reset/save added to it,
// and the result displayed in float text over the top of the script.
// The first time you start accepting donations, you should set both of the numbers below to zero.
// When saving this script, you (the object owner) should touch the donation box object,
// which will then tell you how much has been donated in total and how much has been donated this month.
// Entering this information here before saving will allow you to preserve the 'state' of the script across edits/restarts.
