WadGadget 0.2

New features:

• Mouse input is now suppported, and many parts of the UI can now be interacted with by clicking.
• A texture editor was added, making the TEXTURE browser feature-complete.
• A browser/editor for GENMIDI lumps was implemented, including export to / import from .sbi voice files.
• A new action was added to update existing WAD entries. This works the same as the import action but instead automatically replaces the contents of existing entries, rather creating new ones.
• A new action to move files between directories was added.
• Duke3D/ROTT .rts files are now recognized as WAD files, and embedded .voc files (found inside them) are recognized as sound effects.
• It is now possible to edit the headers of graphic lumps (useful in particular in order to change the X/Y offsets).
• It's now possible to import graphics from a variety of other file formats in addition to .png: .pcx, .lbm, .gif, .bmp, .ppm, .tiff and .xpm. This is accomplished using NetPBM filters.

Minor:

• Escape now only exits the program when viewing a directory, to avoid accidentally exiting the program prematurely. Escape time delay was reduced to 10ms, improving responsiveness.
• Bullet point lists in the help browser are shown with real bullet point characters rather than asterisks.
• In the hexdump view, the UDS-help action now jumps to the relevant section of the document based on the lump being viewed. Other documents will also be shown instead (boomref, etc.) if appropriate.
• The ^W key combo now clears search, rather than ^U.

Bugs fixed:

• A crash was fixed when creating an empty WAD file.
• A crash was fixed when deleting an entry selected in the other pane (thanks skynettx).
• There is no longer a "flash" of the wrong palette when exiting the program.
• A crash was fixed when .png files would fail to import properly.

Cleanups:

• Initial support was added for building using pdcurses.
• The codebase was tidied using clang-format and include-what-you-use.
• Various cross-platform changes were introduced, inspired by @skynettx's Windows port of the program. These lay the groundwork for an "official" Windows port in the future.
