(still in progress, per "//vvvvv" comments):
Update credits and copyright.
Fix some grammar and remove obvious comments.
(For example, stack vars are always destroyed when
"out of context" (i.e, scope, when stack popped),
so no need to comment on it).
Remove wxWidgets error squelching.
"rm_dash_rf*" static functions
Rename all the "rm_dash_rf*" static functions to better
reflect what they actually do (per "finally
misnomer" comment). Not very mnemonic to
name functions on *nix-specific shell command
"rm- rf" that they do not emulate. Only 1 of the 4
so-named actually removed anything.
Remove one unnecessary function (originally
"rm_dash_rf_enumerate"), replaced by
parameter defaults on main recursive function
(originally rm_dash_rf_enumerate_i").
Remove unused parameter "prompt" from
rm_dash_rf_enumerate_i (now RecursivelyEnumerate).
The files_p and dirs_p ints were actually used only
as bools, so make them bools bFiles and bDirs.
Rename "prompt" vars to match ProgressDialog
"message" arg. They do not prompt user to do
anything, they're informational.
files_p and dirs_p were int but used only as bools,
so make them bool for better readability.
