[PATCH] Removes Leftover Techs

[Nikos]

Athenian Gymnasion and Spartan Syssition had a tech pair that had to be removed, as it was removed from all other factions with alpha 17 changes, probably an oversight.

[s0600204]

There are a number of other technologies that aren't researchable from any structures anymore since the rebalance, but still exist in the technologies folder. (I can provide a list.)

Would it be a good idea to include them for removal?

[Niek]

Probably they could be preserved for making civs unique in the future.

[Nikos]

Yeah several of them might be reintroduced or edited to something similar, I'd say let them be.

line 42 in athen_gymnasion.xml in structures.patch​

is indented too much. I think it should have only 2 instead of 6 spaces.

niektb/prodigal_son: Fair enough, I see your point. Although they will still exist in the repository history, making them just a svn copy away.

For reference purposes I've put the list of currently unused techs on pastebin: ​http://pastebin.com/J4Y76dhR

How about removing the old pair_* files that point to techs that are still in use but are no longer paired? (See the end of the pastebin link.)

njm: I agree.

[Nikos]

On the code part, it could be a mistake on my part (you mean it has some unnecessary spaces right?). Those were the first files I ever edited for 0 AD.

If it's so easy to retrieve files, then it wouldn't be a bad idea to remove them, but maybe ask scythe first, he might have plans to use some of them soon. Same with the pairs I guess.
