[dev] [dmenu] Cache on start option?

Is there a cache on start of /bin folders option vs only when we select
the hot key to trigger dmenu?

Reason being, it might be preferred to cache the bin following DWM start
vs, when somebody finally gets to executing dmenu.

ie.

1) Start DWM
2) After start of DWM, execute DMenu -cache (to cache/scan all bin
folders into $HOME/.dmenu).

3) Somebody finally executes DMenu to choose an application immediately
vs. waiting for DMenu to also cache (all bin folders).

VS. Currently,

1) Start DWM
2) Wait for DMenu to be executed by somebody, then somebody has to sit
and wait for DMenu to cache bin folders before choosing their
application.
