Crimson Fields 0.4.7 released

[Jens Granseuer <jensgr@xxxxxxx>]

Hya.

As the second tutorial map seems to need a little longer, I decided to
go ahead and release 0.4.7 rather sooner than later.

The detailed changes for those who haven't been paying attention:

* fixed issues with railroads/railways

* added single-step undo

* added first tutorial mission

* you can no longer start e-mail games against the computer

* maps can be excluded from the skirmish list

* sped up application startup times

* added event groups; if one event from the group is executed it
  removes the others from the game

* replaced (broken) 'nextmap' event with more versatile (and working)
  'configure' event that can also be used to dynamically change the
  player briefings

* 'createunit' event supports setting experience and unit strength

* 'unitposition' trigger can be used with enemy units

* 'research' event can also be used to remove units from the tech list

* removed support for 'terrain = forbidden' from mktileset

* added cf2bmp utility to create map images (--enable-cf2bmp)

* updated translations (de, pl, sk)

Due to the event changes, maps and saved games are not compatible with
0.4.6.

I hope to have a Windows binary package available tomorrow.

Enjoy.

Jens
