The goal of this first installment is to organize the code a bit so it's more readable,
clean up a bit of left over cruft, and manage link configurations (and links in general).

Put back commented out code

- Updated MainWindowTest to catch this problem
- Also implemented initial pass at SetupView unit test

Include support for both param sets

The parameters for calibration were changed in the latest master. QGC
needs to work with both. Hacked in for now, waiting on a true parameter
re-mapping implementation.

There's also a partial fix for the databits and stopbits. I'm unsure how to deal with the logic
around the 'is_cdc' variable, as I can't really follow what it's for.

Controls respect QGCPalette settings. Also added test window.

Since this is generic Qml support not specific to FactSystem

Fixing braces
Changing data plot save files to csv only
Fixing LinechartWidget::startLogging() as it no longer needs to worry about a proper file name being set.

Fixes Issue #1162

Changing the order of the QGCFileDialog::getSaveFileName() function. The idea was to expand the existing QFileDialog version but as we removed the selectedFilter, we might as well make this more intuitive. The options argument is the one trully optional and should be last.
Adding an example to the documentation on how to go about figuring out what file type was returned by these functions.

Removed the “selectedFilter” argument from the QGCFileDialog functions along with references to it in unit tests.
Fixed function declarations and prototypes formatting while at it.
Changed the caption of a few file save dialogs with a more descriptive text (explicitly telling what is being saved).

Added a dialog asking the user about overwritting an existing file.

Remove erroneous use of QFileDialog::selectNameFilter(). No filters are to be selected. The argument selectedFilter is a pointer to a String to receive the filter selected/used by the user.
