Move window logging logic into separate subroutine

[TheCodeArtist]

This is to setup for future tasks :

• to add filters (blacklist/whitelist)
• to add pre-processing hooks

[TheCodeArtist]

Refactored window-logging logic into the following 2 functions() in loggingModule.vb.

• logActiveWindow()
• logStatus()

As the window data is picked from frmMain.lvEntries,
it is tightly coupled with the logging functions and hence references to it exist in the above functions.
