Resect terminal color themes

Adding option to use the users terminal color theme for twad.

Fix woof save behaviour, no cgo

So this should finally fix the behaviour of woof. dsda still seems to ignore -save ... not sure why yet.

• Compiled without cgo, to hopefully fix #8

Add woof and dsda to known ports

Woof and DSDA now added to known ports. They both are based on BOOM so currently the "act" like boom-forks and getting the same parameters.

Bug fixes based on issues

These two issues should be fixed with this release:
#6
#5

v0.20.0

After downloading from idgames twad now offers to import the archive.

v0.18.0

• Add .pke as known extension for mod files
• Some ui and navigation cleanup
  -- Change some keys
  -- Bigger "help" with F1
• Can now "beam" to a specific map of a mod by name via the warp dialog

v0.17.0

• ID Games Browser + download function via F2 key
  Very usable already. Still, quite a bit to do here such as a better download progress, and maybe an "auto install" of the download.

• Custom port configs per game as well as a shared config storage (thanks to @nullstalgia)
  Each game can have it's "own" config for the configured source port by checking the according box in the Add/Edit dialog. As well shared configs can be used which are stored in ~/.config/twad/configs_shared in sub directories per source port to avoid conflicts.

• Couple of fixes and refatcorings as always

v0.15.0

• Now native (experimental) Windows support with some OS specific behavior; though double click and go
• Integrated rudimentary idgames search (F2); in the future download / installation will be possible from here
• Some minor bug fixes and refactoring

v0.14.0

• More responsive layout (that massive header gets hidden on smaller terminals)
• There is now a full keymap on F1
• Option to store a url with a mod and visit with u
• Now stores Add/Edit date so that you can recognize when to check if a new version has been released
• Some code cleanup

v0.12.0

Add archiver lib and security warning for archive import
Minor cleanup
