[FIX] Use system include to suppress warnings (during compilation) caused by the faulty OpenIGTLink header file

[FIX #413] fixed  "warning: throw will always call terminate() in C++11 destructors default to noexcept"

[ADD] possibilty to initiate picking from external position obtained by connector instead of single click

and some style fixes

[ADD] included also opacity weights into VisiTrace implementation --> VisiTrace should be complete now

+ corresponding tests

Optimization still missing.
