Subject: [PATCH] Log Window (#94)

* Split type combobox into system combobox and disc type combobox

* corrected indentation for xaml file

* fixed merge with head

* fixed format

* fixed issues for PR, added KnownSystem.CUSTOM

* removed Updater.cs which ended by error in commit

* fixed GetOuptutName() for new drive/system combobox

* created LogWindow and first tests of output gathering

* integrated all the proof of concept related to stream fetching of DIC output into LogWindow

* working on LogWindow\ncreated more efficient output matching management, improved handling of process termination

* created Tasks file\nmoved some methods there, created DumpEnvironment to manage are arguments

* moved additional methods to Tasks to make it more modular

* changed StartDumping flow to avoid returning if extra tools are not found

* moved main dump workflow into Tasks class

* created specific DumpResult class for better error reporting/management

* fixes

* fixes Dispatcher thread issue with progress bar

* continued refactor
- split EnsureDiscInformation into an additional EnsureCorrectInformationForSystemAndMediaType
- proof of concept of using custom extensions to enum types to give better functionality (and encapsulation)
- changed cmb_MediaType to keep a List<MediaType?> and got rid of Tuple<string, MediaType?>

* restored GetDiscType functionality

* fixed btn_StartStop enabled on EnsureCorrect... error

* fixed whitespace

* fixed indentation

* merged conflicts

* moved log window

* working on LogWindow resize/location behavior

* working on message logging in LogWindow

* added working integration between MenuItem for LogWindow and its visibility status, fixes issues with positioning and visibility, correctly bound Verbose flag to property

* finished integrating LogWindow, added some verbose logs

* added logs

* fixed include order

* added option to show log window at startup, removed useless QuietMode property from MainWindow
