UXUI Polishing Part 2: Platers, G-Code Viewers, ProjectLayer and SpoolManager

[neofelis2X]

Good Evening. It took a little longer than expected, I had to dig a bit deeper for some things. With this PR I continue to refine the ui of Pronterface. Example Plater: Example Spool Manager:

This was tested on MacOS and Windows, just like last time. I used real files and tried to test all situations I could think of. Here's a non-exhaustive list of changes, but it's probably better to look at the tools directly:

STL and G-Code Plater

• layout update
• groups and structures that make it easier to understand
• added StdDialogButtons
• buttons are greyed out when not available
• changed the way the 'Cutting Tool' is loaded

Excluder + G-Code Viewer:

• minor layout update
• added 'Close' button to toolbar
• rearranged buttons in the toolbar
• made sure the right toolbar is loaded
• added SetTitle for Excluder

ProjectLayer Control

• minor layout update
• added 'Reset' and 'Close' buttons
• added the 'reset defaults' feature
• buttons are greyed out when not available
• added gettext markups for all strings!
• added a 'Status' to the infobox and send now all former 'print' to that
• added warning when a value is not valid
• 'Direction' setting saves now the index and not the string of the choice
• fixed 'Calibrate' feature, expected integer
• fixed 'First Layer' feature, expected integer

SpoolManager

• resized and optimised main dialog
• fixed dark grey background
• combined statusbar and 'Close' button
• buttons are greyed out when not available
• layout update of 'Add Spool'
• rearranged layout of 'Edit Spool'
• use modal dialog for add and edit

I hope you like the changes. If so, I have plenty of ideas for further improvements.

Wow, thanks for the thorough review. Some very good points you made. At the moment I do not have much time to spare, but I will add the changes in the next two weeks.

Hi Rockstorm, great that you already looked at it. I will add the changes and check if everything is fine on windows.

One question: Am I seeing this correctly that every file that contains string-translations _( ) need to include this line: install_locale('pronterface') ?

Both is correct.
