Add Bitsquare.iss file as produced by javapackager

This file was produced by adding a `-v` flag following the `-deploy`
flag in `package/windows.bat`. The creation of the file is reported by
javapackager as follows:

    Config files are saved to
    C:\Users\CBEAMS~1.WIN\AppData\Local\Temp\fxbundler5661616451276716144\windows.
    Use them to customize package.

Subsequent commits will customize this file, primarily for the purpose
of avoid the dreaded 'missing dll' errors mentioned originally in
d16c274 and detailed at https://bitbucket.org/shemnon/javafx-gradle/issue/43.
Customize AppId and PublicationUrl entries
Configure the inclusion of missing .dll files
