'make installer' will now spit out an openvpn-gui-installer.exe. The
location of the required makensis tool can be specified by appending
MAKENSIS=/path/to/makensis to the configure command line. Otherwise
it's searched for in your $PATH. The installer target is only available
when makensis is available.
You can now define up to how many configuration files you want
to support by stating something like
./configure MAX_CONFIGS=150 ...
when invoking configure. Default value remains 50.
