st-meta-vim-full: change currentBg, introduce currentFg, update shortcuts

cyclefonts: keybind to cycle fonts (agree with st-xresources-signal-reloading)
This patch is an update to the 20210604, which fixes zoomreset. Because the cyclefonts function doesn't change the defaultfontsize variable, zoomreset function resets all fonts to the size of the first one loaded. With this patch, zoomreset will reset the font to the specified fontsize

Justinas Grigas	02739346a8	cyclefonts: keybind to cycle fonts (agree with st-xresources-signal-reloading) This patch is an update to the 20210604, which fixes zoomreset. Because the cyclefonts function doesn't change the defaultfontsize variable, zoomreset function resets all fonts to the size of the first one loaded. With this patch, zoomreset will reset the font to the specified fontsize	2026-01-22 08:22:36 +01:00
