Some cleanup.

Unfortunately this seems to care about our syntax highlighting and I
can't find how to change the paragraph sign's color.

be given - this will flash the frame's border, enabling contextual help.

Add possibility to show the user guide with a specified tab opened. Use this to link to the Preview section from the preview menu.

This made a small TODO necessary: dedicated <section> parent tags now
respect colors. Also, an oversight was fixed where color names would not
run through our color picker.

More preview menu fun: comment out all content, copy all content to comment (quick 'backup'), collect comments at bottom of file

Add preview editor menu entry to paste to new line (vim-style paste), cut whole line if selection is empty.

This is a quick keyboard combination to move keys around. Add shortcut
for 'quicksave'.

Restoring the selection is now more intelligent and cleaner. A little refactoring gets rid of empty undo stack entries.

the Preview editor.

Load the user's textual changes in the preview editor back into the parser before performing a transformation, thus taking them into consideration.

The chain should now be closed... getting there at least.

Trying not to use the term 'GUI' in the Preview menu... show the application's name instead (at the time of the preview click)

In an afterthought, start the undo history after the document was first inserted (no undoing back to blank)

The Preview integrates so nicely that we now do keep a local INIParser copy. By performing all transformations on that one, they now behave intuitively and can be applied one after another.

Quick fix: a signal also triggers disabled menus, so we check this back (to disallow getting to the Preview without an application).

Add 'new tab' preview menu, listen to the print command (to show preview) in the preview itself, the Logger and the About window. Show the logger on STRG+L from the preview and about windows.

The oxygen PNG icons have been removed (they were not used anymore), new icons have been added and the globe and forumla icons replaced by svg icons. All icons are either self-made or from breeze/elementary.

Some filters had unnecessary constraints that have been removed. Some periods in seconds were expressed as a number and have been replaced by an expression for clarity.

Move the data merging strategy to 2nd 'column', add troubleshooting help section for the PATH variable (link to SNOWPACK online help)
