Bug#746538: espeakedit: Please update to use wxwidgets3.0

[Samuel Thibault <sthibault@debian.org>]

Hello,

I have updated espeakedit to the latest upstream revision, 1.48.03,
which already includes almost all wxwidgets 3.0 fixes.  I have kept the
missing ones as patches.  Bumping the build-dependency to wxwidgets 3.0
however brings a startup issue:

An assertion failed!

../src/gtk/font.cpp(337): assert "IsOk()" failed in GetPointSize():
invalid font

Backtrace:

wxFont::GetPointSize() const
wxEntry(int&, wchar_t**)
__libc_start_main

and then the interface seems to show up fine, but I'd rather avoid
uploading that.  Would you have any idea about what is going wrong?  I
really don't know much about wxwidgets.

Samuel
