Foereaper ee1b174a27 [Cleanup] Part 1
This is the first of several cleanup commits, specifically directed towards the dependencies.

This commits removes the old, deprecate precompiled openssl and mysql libraries, as well as started restructuring of shared and deps folder.

This has not been tested on Linux yet, and the pre-built SLN files have not yet been updated.

# - Try to find the OpenSSL encryption library
# Once done this will define

# OPENSSL_ROOT_DIR - Set this variable to the root installation of OpenSSL
#
# Read-Only variables:
# OPENSSL_FOUND - system has the OpenSSL library
# OPENSSL_INCLUDE_DIR - the OpenSSL include directory
# OPENSSL_LIBRARIES - The libraries needed to use OpenSSL
