Find dead links

[chcg]

@bruderstein
there are some dead links in the plugin list, e.g.

• http://www2.brotherstone.co.uk/npp/NppMenuSearch075.zip
  (also https://sourceforge.net/projects/nppmenusearch/files/v0.9/ exists)

• http://www2.brotherstone.co.uk/npp/NotepadSharp_1.5.0.zip
  (seems github https://github.com/jvdanilo/NotepadSharp doesn't exist)

Maybe we could add a check for dead links at server or client side for the complete list.

Added a short test with x86 unicode downloads and https://wummel.github.io/linkchecker/index.html added a minimal website with the download links.
pluginlinksx86.txt
leading to result:
linkchecker-out.txt

• added issue Update PluginManager data peter-frentrup/NppMenuSearch#7 for an update

[chcg]

Tested with wget(https://eternallybored.org/misc/wget/ for windows):
wget64.exe -i pluginlinksx86.txt -o log.txt
and input list:
pluginlinksx86.txt
result is
log.txt
