 version update to ipe-7.1.5

 New:

 1) ipe now uses the turbo-jpeg API to read jpeg files. AFAIK this is
 problematic in MacPorts, since the jpeg and libjpeg-turbo ports conflict,
 and there is no way to install both. I therefore add a patch to replace
 the relevant code with the standard jpeg API. Also, I set the jpeg
 dependency as
 {{{
 path:lib/libjpeg.dylib:jpeg
 }}}
 as mentioned in #38907. Hope this is the best way to go.

 2) I added a variant to compile the optional "qvoronoi ipelet", since this
 is now part of the default Windows binary. This currently needs a minor
 patch to compile with clang.

 3) I also used the opportunity to update my maintainer e-mail address.
