Merge https://github.com/archey/blackarch into wpscan
wpscan: Clean and fix.

This is a nearly-complete rewrite of the PKGBUILD file.
Add 'python-netaddr'.

This is a dependency for 'dnsrecon'.
sqlmap: Switch to the Git repo.

The SVN repo was deprecated by the upstream.
dnsrecon: Clean up and fix the version number.

We get the version number from the README file now. It's prone to
breakage but better than nothing.

hotpatch: Clean up the PKGBUILD file a bit.

This...
  - Makes `pkgname` a scalar value.
  - Removes the package name from the description.
  - Changes some quotation marks for consistency with other packages.
  - Removes the `pkgver` function.
  - Removes the `options` list. The `!strip` option makes `makepkg`
    refrain from stripping symbols from ELF files.
  - Removes a blank line at the end of the file.
  - Moves around a couple of lines.
hotpatch: Remove `gcc` as a dependency.
xorsearch: Make the PKGBUILD file more idiomatic.

This...
  - Removes the contributor comment. We are supposed to have a
    contributor list. I meant to put that together a while ago.
  - Changes the license format. Licenses not in
    `/usr/share/licenses/common` should have `custom:...` in their
    license lists.
  - Changes the indentation from tabs to two spaces.
  - Uses `install` instead of `mkdir` and `cp` to install the program.
  - Adds `pkgver` to the source filename.
yara: Make some tiny style changes.

This...
  - Makes `pkgname` a scalar value.
  - Removes the package name from the description.
  - Removes `gcc` as a dependency. `gcc` is only needed during the build
    but since it is part of the `base` group, we do not have to list it
    in `makedepends`.
Add 'CONTRIBUTORS'.
CONTRIBUTORS: Organize a bit.
sqlmap: Switch to version 1.0dev.

Version 0.9 was not working. 1.0dev is the head of the git repo.
Add more items to the package-specific gitignore file.
CONTRIBUTORS: Clean up a bit.
