Update Spanish translation for currently running and version history strings, addresses #1429

[billymeltdown]

Updates Spanish translations in es.lproj for the "You are currently running..." and "Version History" strings.

Addresses #1429

I ran these translations by a friend who's first language is Spanish, so they should be reasonably idiomatic, but let me know if not, happy to adjust.
