Bugfixes in SVN rev 130

Misc bugfixes in rev 130:

fix -datadir with relative path autostart is now off by default except on windows fix occasional “vector iterator not dereferencable” assertion when compiled with msvc fix readlink compile warning on linux build use sys/param.h and BSD define instead of BSD -paytxfee switch, e.g. -paytxfee=0.01

No, that’s not what it is.

-paytxfee allows you to include a transaction fee with your transactions.  If transaction confirmations become slow, you can get priority by using “-paytxfee=0.01”.  Any transactions you send would cost an extra 0.01.  There’s no reason to use more than 0.01.

It’s just there in case we need it.  It probably won’t be needed, and it can be explained more if we do.
