Subject: [PATCH] Allow management of resources and modules paths

SDR++ uses the config file to determine the location of modules and

resources to load. While this is mostly static in other distributions,

in Nix it changes very often.

This commit adds some functionality to the config manager to replace

`@prefix@` in the values of the keys `modulesDirectory` and

`resourcesDirectory` to a dynamic path. On save, the change is reverted.

The prefix path used is either the installation directory, or the

content of the `SDRPP_PREFIX` environment variable, if present.

Subject: [PATCH] Fix sdrpp breaking every time the package is rebuilt.

On NixOS, the INSTALL_PREFIX changes on every rebuild to the package, but sdrpp

fills it in as part of the default config and then installs that config

to the users home folder. Fix this by not substituting @INSTALL_PREFIX@ in the

default config until runtime.
