* Fix missing dependency feature for objdiff-gui
* Update .gitignore
* Add enter and back hotkeys
* Add scroll hotkeys
* Add hotkeys to select the next symbol above/below the current one in the listing
* Do not clear highlighted symbol when backing out of diff view
* Do not clear highlighted symbol when hovering mouse over an unpaired symbol
* Auto-scroll the keyboard-selected symbols into view if offscreen
* Fix some hotkeys stealing input from focused widgets
e.g. The symbol list was stealing the W/S key presses when typing into the symbol filter text edit.
If the user actually wants to use these shortcuts while a widget is focused, they can simply press the escape key to unfocus all widgets and then press the shortcut.
* Add Ctrl+F/S shortcuts for focusing the object and symbol filter text edits
* Add space as alternative to enter hotkey
This is for consistency with egui's builtint enter/space hotkey for interacting with the focused widget.
* Add hotkeys to change target and base functions
* Split function diff view: Enable PageUp/PageDown/Home/End for scrolling
* Add escape as an alternative to back hotkey
* Fix auto-scrolling to highlighted symbol only working for the left side
The flag is cleared after one scroll to avoid doing it continuously, but this breaks when we need to scroll to both the left and the right symbol at the same time. So now each side has its own flag to keep track of this state independently.
* Simplify clearing of the autoscroll flag, remove &mut State
* Found a better place to clear the autoscroll flag
DiffViewState::post_update is where the flag gets set, so clearing it right before that at the start of the function seems to make the most sense, instead of doing it in App::update.
This allows users to "map" (or "link") symbols with different names so that they can be compared without having to update either the target or base objects. Symbol mappings are persisted in objdiff.json, so generators will need to ensure that they're preserved when updating. (Example: d1334bb79e)
Resolves#117
