ethash is set for ETC instead of etchash, leading to crashing miners

[kid-alan]

When selecting an ETC flight sheet, the ethash algorithm prototypes are being used instead of the correct etchash.

This results in miners crashing with the default flight sheet. Users are required to manually open miner settings and set etchash there. It appears that ETC is incorrectly mapped to the ethash algorithm instead of etchash.
