Progress Log

# Commit 4176f29 - Adds some initial code to create a new actor sheet that'll represent vehicles. - It also implements the vehicle stats/characteristics. - Still tempted to add a '+' sign before the Handling characteristic when the value is positive.  # Commit add4390 - Adds the Effects tab by reusing the existing EffectsView. - Modified the selection of stats that can be affected when the effect is tied to a vehicle. - Fixed the label when creating a new actor of vehicle type.   # Commit 7b577b9 - Adds the Details tab and expands the template to include additional fields.  # Commit 879da53 - Adds the Inventory tab and expanded the template to also include currency as one of the things it can hold. - Currently nothing can be equipped and all active effects are suppressed. - Nothing can be "dropped to the ground" either but there's no plan to include that category unless a compelling use case is presented.  # Commit f2a99d7 - Adds the Crew tab and expands the template to hold all the new information. - Users can create new roles directly from the sheet and drop skills and/or actors to it. - Moving to/from a role can be done via drag & drop. Although there is no sorting inside a role. - I'm reusing the InventorySortSlot for sorting passengers but eventually I'll rename said component to be more generic. - Made some improvements to the sorting of equipment on the Inventory tab. These improvements will be ported to the character's Inventory tab at a later day.     # Commit db2d5d5 - Adds the Skills tab which uses the role data to list the skills each character can role directly from the sheet. - A player can only roll for characters they own. - Made small changes to the ActorTile component.  # Commit b2d41e8 - Adds the VehicleWeapon item type - Most of the code for the Weapon item type was generalized in order to use it for vehicle weapons as well  # Commit 81246c5 - Adds the Combat tab - Selecting a weapon will trigger a popup with a list of characters. The list contains only characters that are assigned to a role which also lists the weapon skill. - Similarly for repairing a Critical Hit. - A new setting was added to specify the skill typically used to repair hits (it defaults to 'Mechanics'). - Vehicles weapons can now be equipped.    # Commit e4b93cd - Users can now move items from a character or vehicle's inventory to another one so long as they have enough permissions on both. # Commit e3e9111 - Modify the name of Critical Injuries to hint that they are also used for Critical Hits - Cleaned the list of attributes presented on the after effects dropdown - Shows all possibilities regardless of the parent container - Added icons to represent the type of actor they can affect - Added a new option to edit the encumbrance value directly (this can be helpful to inflate the encumbrance value for items that change encumbrance or to symbolize extra encumbrance from passengers)
