Proposed changes for updating wxWidgets project wizard:
* Drop support for outdated wxWidgets 3.0 and 3.1. These versions are outdated and unsupported so it makes no sense to use them in a new project. Removing them allowed to simplify the wizard code.
* Do not allow using non-Unicode configuration for wxWidgets 3.3 and newer, where Unicode is the only text encoding supported.
* On Windows, link to Winsock2 unconditionally. wxWidgets older than 3.2 used older Winsock version so we needed to provide a choice.
* On Windows, link to gdiplus and msimg32 for wxWidgets 3.3 and newer, as required there. wxWidgets 3.2 and older load functions from these libraries at run-time from DLLs.
* Do not link to wxAdvanced, the library does not exist in wxWidgets 3.2 and newer.
Unfortunately, I do not know how to create an SVN patch, but the changes can be previewed here:
