The built-in extension for ini files defines the language for properties
files, like .gitconfig and .conf, which are language agnostic properties
files that should be represented by a language agnostic icon.

The Seti icon theme defines a cogwheel icon for properties files, but
additionally associates files with the .properties extension with Java.

Coincidentally, the first file extension listed for the properties
language is ".properties", which causes the build script for Seti to
make the Java icon the default icon for all config files, and just
overrides the icon for files like .gitconfig.

This should be the other way around, so the Java icon for .properties is
the exception for properties, and not the default.

Fix:

This patch moves the .conf extension to the top of the list of file
extensions in the built-in ini-extension and reruns the Seti build
script, making the config icon the default.

Fixes microsoft#158453.
