Subject: [PATCH] clipablewire.cpp: Dropping usage of register storage class

The register storage class has been depreacted in C++14 and completely
removed in C++17. Thus resulting in buils errors such as:

clipablewire.cpp:55:2: error: ISO C++17 does not allow register storage class specifier [-Wregister]
