Some minor bug fixes:

A. Special tile lays
Currently special tile lays had hardly any checks for its validity.

Examples:
a) In 1889 the port tile can be laid on a hex already containing
a yellow broad curve town tile.
b) In 18AL the lumberjack tile can be laid on a hex already containing
a yellow broad curve tile.
c) In 1830 the D&H allows upgrading to green tiles if a yellow tile was laid 
already.

The following changes prevent this:
- Special tile lays always increase tile colour number.
- Special tile lays always check the allowed tile colour of the current phase.
- Add tile="57" to D&H special property

A solution for the problem that the UI suggest a potential Pfalzbahn tile lay 
in 1835 in yellow (as reported by John Galt) is not possible yet: The 
Pfalzbahn special tile lay has no specific tile specified, thus the check if 
any tile is available for that hex is only done after the hex gets selected.

B. Configuration import
The import functionality for the new profile files does not work currently 
(legacy config files do work). This will be fixed in the next release.
