0.5.4: Integration with Azgarr's Fantasy Map Generator

The main feature of this update is integration with Azgarr's awesome Fantasy Map Generator. This is how it works: you can click any settlement on a map in FMG (and then a tiny button with a map icon on it) and MFCG will build a plan of that settlement taking into account its size and location. And vice versa: you can click the "Overworld" button in MFCG and for the current city FMG will generate a world around it with rivers and oceans, neighboring towns and states. Nothing fancy but we hope it may be useful.

By the way it reminds me that this generator needs a better name...

Other changes:

• Improved labels placement. Still far from perfect.
• Improved neighborhoods coloring. More visible on large maps with too many tiny buildings.
• You can now choose one of three font sizes for the labels ("Annotations" submenu).
• Coast and rivers are drawn slightly differently (better?) in "hatching mode". I'm not sure anybody uses it, but I do :)
• Some non-critical bugs are fixed.

That's all for now.
