Revert "config-parser: Catch negative numbers assigned to unsigned config values"

The reduction in range limits does have an effect for color values,
which are expressed as hexadecimal values from 0x00000000 to
0xFFFFFFFF.  By limiting the range to INT_MAX, color values of
0x80000000 and up are in fact lost.

This reverts commit 6351fb08c2.
