Graphics Update/New UI for VPR

[SebastianLievano]

Description

A complete revamp of VPR's UI.

• Moved all menu options to separate dropdown menus
• Moved button initialization to main.ui file
• Significant changes to callback functions to allow for new placements
  OLD UI:

NEW UI:

CODE CHANGES:

• Essentially deleted most of buttons.cpp/.h (old button creation functions) and added new files ui_setup.cpp/.h which contain gtk signal connections for callback functions, as well as show/hide options for diff. menu sections
• Rewrote all initial setup functions to:
  a) Stop calling each other
  b) Call either the setup or hide functions for different menu options depending on which ones they show
• Edited callback functions to:
  a) Function with app->get_object() which works on any object in the application
  b) have _cbk in their name to make their purpose clear and prevent accidental calling in any other context
  c) Be better documented (documentation was pretty good before actually, just added doxygen format)

Motivation and Context

Old UI was essentially unusable on smaller screens. Due to the manner in which buttons were created/initialized, they simply appeared in an unscrollable stack on the side. To increase usability, I sorted the menus into different dropdown options. This resembles industry standard.

How Has This Been Tested?

As each new button was created and added, its behavior was tested and compared to the same buttons performance on the master branch. To test different setup options, the cmd line was used to run vpr graphics in different stages.

Types of changes

• Bug fix (change which fixes an issue)
• New feature (change which adds functionality)
• Breaking change (fix or feature that would cause existing functionality to change)

Checklist:

• My change requires a change to the documentation
• I have updated the documentation accordingly (Will Update Soon, writing a glade/gtk quickstart which will be linked)
• All new and existing tests passed

Failures so far are due to all servers busy; Sebastian tells me they passed previously. Please re-run the failed tests, but if it's holding you up I can merge in advance of those.
