Regression Test Script Problem

Another problem was discovered, this time with the regtest script.  For convenience, my PATH variable contains the current working directory ("."), so I didn't notice this problem.  By default (and for safety), the PATH variable does not contain the current working directory.  So the regtest script fails to find the "ibcp" program.

Therefore, regtest (actually regtest.in) was modified with a "./" in front of ibcp so that the regtest script will run the program in the current working directory.  No new files were uploaded to Sourceforge, but a new commit and tag release0.1.16b was pushed to GitHub.  The Windows batch file regtest.bat is not affected since Windows by default will look in the current working directory for a program.
