bitcoin+truecrypt: tiny run-script to make using tc'd wallets easier

this script checks to make sure a specific wallet file exists before running bitcoin

this might be desirable if one is opening a wallet from a truecrypt drive, and wants to ensure the wallet exists and is writeable before opening the client

I found it useful because I kept accidentally opening up the client w/o mounting the tc drive. Also, my wallet permissions changed yielding qt start errors which took me a while to figure out whilst I was deleting database/blockchain files erroneously. Since I will likely forget about the cause of the error sometime in the future, this script will remind me for quick truecrypt wallet re-accessing.

To use just change the paths below to match up with your truecrypt wallet location and bitcoin-qt client path.
