vifm: Add additional configuration and functions

Renamed fuzzy find functions to simpler and more logical names:
`fzf` to find and select anything recursing from current directory.
`fzfcd` to find and enter any directory recursively under current one.
`fzfhome` to locate and select anything from user's home directory.

Added shortcuts for above commands:
<space>f `fzf`
<space>c `fzfcd`
<space>F `grep` from current directory.

Added shortcuts to create and extract archives:
xx to extract selected archive.
xa to archive selected files, giving name of file under cursor.
xc to archive and compress selected files, giving name of file under
 cursor.

Move ability to sync current pane to other one from mapping (c-y) to
command (`:syncme`). This is a command only used once in a while and
does not necessarily need its own full mapping. Additionally, having it
as an invocable command mirrors the built-in `:sync` command to do the
exact opposite - sync the other pane to the selected one.
