#10 Make RDE USB-friendly

[Anonymous]

RDE v1.0.1.1 stores main settings in the registry. This
doesn't make RDE well suited for running from an
ordinary USB memory.

There should be an option to store settings in e.g. an
ini-file in the same path as RDE.exe.

Suggestion: Upon start of RDE, first check if there is
an ini-file with the main settings in the same path as
the main executable.
* If such a file exists, the registry is ignored. (USB
mode)
* If there isn't such a file, look for settings in the
registry. (Installed mode)

Furthermore, one could also consider adding an option
to RDE's options menu, for creating an ini-file with
the main settings. Alternatively, a sample ini-file
with example settings could be included in the
distribution.
