Please support wxWidgets 3.0 also

[swt2c]

I noticed in e46d7f9 that you switched to wxWidgets 3.1 APIs. It is fine to use these APIs but unfortunately most Linux distributions have wxWidgets 3.0 and won't update to 3.1 as it is a development release (with unstable API/ABI). It would be appreciated if you could add back support for 3.0 (keeping 3.1 support as well is fine).

They can't/won't. It's not feasible to support both versions. Also please search past issues.

#635

The inclusion of wxWidgets v3.1.0 is way older than that: #173.

True enough in e46d7f9 (then #635) I indeed changed some deprecated methods of v3.0 into the new way of v3.1x, breaking the illusion of compatibility with v3.0x.

We have enough trouble providing advice for v3.1x usage and compilation at this point to not bother with yet-another-antiquated version v3.0 that came into being in November 2013.

Now compiling wxWidgets from the reference tar https://github.com/wxWidgets/wxWidgets/releases/download/v3.1.1/wxWidgets-3.1.1.tar.bz2
is easy enough, and is described in https://github.com/cjcliffe/CubicSDR/wiki/Build-Linux.

Alternatively, you can take @loughkb scripts as inspiration.
