Reapply [r13622], removed by [r13636].

- Astyle: Revert last commit, because fixes one issue creating other.

- Clangd_client Remove dead/unused code, no additions or code changes

- Astyle: Replace angle brackets with double quotes when including the library (thanks Krice).
Compilation fails if astyle library is installed in the system.

- Clangd_client Fix Linux: message hiding behind "Manage plugins" dialog window when using focus follows mouse.
change reference to "Old CodeCompletion" to "legacy CodeCompletion"

- lib_finder: Fix mv destination path (thanks LETARTARE).

- Plugins: Update link to codeblocks.org in manifests.

* lib_finder: Fix plugin loading on Linux (ticket #1517).
The leading "lib" part from "lib_finder.so" is stripped inside C::B, so the plugin cannot be loaded.
The obvious solution is changing the output file from "lib_finder" to "liblib_finder",
but C::B strips the first "lib" when saving the project so this does not work.
Fix the issue renaming "lib_finder.so" to "liblib_finder.so" in the "update" script
and removing the old "lib_finder.so" from the output folder.
