Helper functions for pinnwand providers and more!

Provider news in 3.2.1 from 3.2.0:

• Add bpa.st as a provider.
• Add paste.rs as a provider.

New features in 3.2.1 from 3.2.0:

• bpa.st is using a software known as pinnwand which is an open
  source pastebin software: https://github.com/supakeen/pinnwand

  So now we have generic helper function to easily add other pinnwand
  providers in the future.

Max retries option

New features in 3.2.0 from 3.1.2:

• We now count how many retries we've done and abort after a set
  amount of retries. This is to avoid infinite retry loops.
  How many times we retry is defined by webpaste-max-retries which
  defaults to 10.

Minor bugfix in webpaste-paste-buffer-or-region

Minor bugfix in webpaste-paste-buffer-or-region

There was a bug that made the function not work at all if you had a
newly opened file and never had an active region in that buffer.

New paste function

New features in 3.1.0 from 3.0.2:

• New function to do pastes has been introduced, it's named
  webpaste-paste-buffer-or-region and selects to paste the buffer
  or the region depending on if you have a region active or not.

Major release with hooks instead of pre-configured options

Breaking changes in 3.0.0 from 2.1.0:

• Removed simpleclip support, use a custom hook instead:
  https://github.com/etu/webpaste.el#copy-url-to-the-clipboard
• Removed sprunge.us as provider in
  5c742bf due to hosting issues for
  the foreseeable future.

New features in 3.0.0 from 2.1.0:

• Add support to parse language of file from shebang
• Add flag to totally ignore language for all providers. This flag is
  named webpaste-paste-raw-text and if set to t webpaste won't do
  any language detection. This is available as a customizable variable.

Provider news in 3.0.0 from 2.1.0:

• Add nix language to some providers
• Add toml language to some providers

Project news in 3.0.0 from 2.1.0:

• We had 25 commits by a total of 2 authors since 2.1.0 that was
  released on 27th of January 2018 (about 339 days ago).

Minor bugfix release

Possibly breaking changes in 2.1.0 from 2.0.0:

• Removed Emacs 24.3 from travis testing, request.el doesn't support
  it anyways. So it's permanently not supported anymore.

Bug fixes in 2.1.0 from 2.0.0:

• Fix of duplicate elements added to alists by @raxod502
• Fix of broken builds by @DamienCassou

Project news:

• We had 11 commits done by a total of 3 contributors since 2.0.0
  that was released back in October (about 3 months ago).

Major release with new provider-format

Breaking changes in 2.0.0 from 1.5.0:

• New provider format which is just much easier to work with and to
  debug if something breaks. It's just a regular alist now without
  macros and not any magic functions running when declaring the list.
• Rename webpaste-paste-text and webpaste-paste-text-to-provider to
  be in "private scope" since they aren't meant to be used by the end
  user. So if you use them, just add a second dash after webpaste.

Provider news since 1.5.0:

• The integration tests still runs once a week, but now we also run
  them for pull requests and all commits in general. One change is that
  we don't run them for all versions of emacs but one (25.3). Github
  gists is also excluded since they only return 403 Forbidden when you
  paste from travis anyways.

New options since 1.5.0:

• You can now add hooks to the return url function to have custom
  handlers for returning the URL to you. Simply add-hook to
  'webpaste-return-url-hook.

Project news since 1.5.0:

• 15 commits by one contributor and documentation updates.
• Lot's of restructuring and changes overall.
• Better provider format
• Repairs of the build system
