Added temoprary Debug/Test UV operator

This is very handy for testing isolated functions which are needed with packing
Will be removed once it's not needed anymore

Implemented a function to compute the area used by UV charts

This will be handy when calculating the used/wasted space during packing

Very minor wording change for menu entries

Add menu entries for de/select mesh operators

Add back the old hide/reveal functionality as seperate operators.

They can be accessed with Ctrl+H for "deselect 3d mesh" (Shift for unselected) and Ctrl+Alt+H for "select 3D mesh".

ToDo: Decide on final naming together with stakeholder artists

Fix for recent commits: Fix an error, silence warnings, clean up unused code

Reveal hidden UVs for all unwrap modes

Make unwrap ops reveal hidden UVs since they're taken into account anyway

Proper Hiding: Make selection operators ignore hidden elements

Implemented "real" hiding of UV elements

Previously it wasn't possible to hide elements without altering the BMesh selection state

Clean-Up commit

* Remove debug prints
* Remove Warnings
* Correct code style (whitespace, formating, line length, etc.) according to check_style_c.py

Fix for missing parameter

Made incremental snapping intervalls smaller for UV editor

Before the intervall was set to 0.125 which effectively resulted in 8 positions across the UV space (per axis).
I halved that value, holding shift enables an even finer movement.

Added "Scale to bounds" operator to scale selected islands to UV boundaries

Options:
* Keep aspect ratio: If checked the aspect ratio of the selected uv islands is preserved
* Individual: If checked the individual uv islands are all scaled to fit the bounds, otherwise the selections are scaled as a whole

Note: Menu locations/shortcuts are to be discussed with users and not to be seen as final

Quick fix for missed parameter

Changed the row of bool arguments for construct_param_handle() to an int flag argument

While doing this I added an "all_faces" check to include all faces in parametrizer even if implicit argument is set (needed for shortest path computation).
