Merge #93: Introduce SPDX license identifiers

bb5b5cf Introduce SPDX license identifiers (Tobin C. Harding)

Pull request description:

  Licenses are boring as hell, so is are all the comments at the top of each file. This patch makes no comment on the merit of license comments in each file, rather this patch reduces the license comment to the minimum possible with no loss of meaning - an SPDX license identifier.

  Note also please that we remove the "written by" comments as well for the following reasons (discussed recently on rust-bitcoin repo):

  - they are not descriptive because many devs contributed
  - they have a tendency to include the wrong date because of cut'n'pasta
  - all this info is in the git history
