[oss] CNS Seemster Planning and Calendar

[Razvan Deaconescu]

Hi, everyone.

We've published the semester planning and calendar on the Calendar wiki
page[1]. We've updated the lecture planning on the rules and grading
page[2]. We've added entries for lecture tests into the cs.curs.pub.ro
calendar as well[3].
