End of RSoC participants application

As announced, the applications are now closed. We currently have a little bit less than 25 applicants, this is incredible. They are all encouraged to join the #radare channel, and to submit (at least) one (non-trivial) patch to the radare2 codebase and one test case to radare2-regressions (any github issue, including closed is ok for writing test) to allow us to check that they know some code :) We can not afford to accept everyone, and we apologize for this: we should only be able to pay two people.
