[Tagging] Aerodrome types

[John Packer]

Martin,
Sorry, I should have talked a little about the history behind this before.

Initially aeroway=aerodrome used the key type=* to further classify it's
type.
Nowadays, the key type=* is infamous because it is the de facto way of
especifying relation's types, and therefore shouldn't be used for anything
else.
Consequently, people started moving away from using type=* to using either
aerodrome:type=* or aerodrome=*.
But type=* it still used much more than both aerodrome=* and
aerodrome:type=* together. Probably it was used on earlier imports of
airport data.
Below you can see values of the key type=* when used together with
aeroway=aerodrome around the globe:

public: 2349
multipolygon: 284
military: 281
civil: 232
private: 173
military/public: 68
public;military: 38
non-public: 37
destination_sign: 30
joint (civil and military): 25
civil / military: 22
joint: 13
public/military: 13
civilian: 10
public / military: 10
airstrip: 8

To make this list shorter, I removed from this list all values that
appeared less than 6 times, and "merged" the values when all that changed
was some letter's case or white.

I am working on the key's aerodrome in the hope it can substitute the key
type=* on classifying an aerodrome, because it conflicts with relations
like multipolygon (as shown above).

I will also include this information in the wiki page Key:aerodrome
