Win Setup: Added support for non-admin installations

[FlorianReimold]

Admin: install to C:\Program Files\eCAL Normal User: install to C:\Users\USERNAME\AppData\Local\Programs\eCAL\

Environment variables (PATH) are set for all users or for the current user only if in non-admin mode.

ecal.ini will be in C:\Program Data\eCAL\ecal.ini in both situations.

I made this a draft, as I would like to get some feedback regarding the install path, first. In "normal" installation mode (as admin), the installation path is changed from C:\eCAL to C:\Program Files\eCAL. The latter one seems more reasonable, but I would like to know if the former (old) path was chosen for a reason.

The line is: https://github.com/continental/ecal/blob/c70f7891fef177e4211ccdd598f3f92d7250becc/cpack/innosetup/ecal_setup.iss.in#L40

Actually I do not know. I think C:\Program Files\eCAL is totally fine 😄

But in general any install location would (should) work.

The old path C:\eCAL was chosen to allow to edit the configuration file ecal.ini that was this time in the ini subfolder of the installation. But I would prefer to use C:\eCAL for all variants of installation. It's easier in case of documentation or any kind of support.

(Sorry for closing and reopening, just back from vacation ;-)).
