Properly clear the last entered character

When enter is pressed, passwd[len] will be set to '\0'. Pressing
backspace is supposed to remove the last entered character.

But currently, the clearing has an off-by-one, as in setting
passwd[len] to '\0' just like enter would do.

You can also verify it by imagining len=1 and that it's impossible to
clear passwd[0] by pressing backspace with the current code.

rm trailing whitespace in README

syntax fix

there can only be one window in the event

Fix resize with multiple monitors and portrait mode

When connecting/disconnecting a portrait monitor, the
XRRScreenChangeNotifyEvent height & width are reversed due to the XRandR
rotation; detect this and DTRT.

bump version

add arg.h and util.h to Makefile

clarify colors in config.def.h

move config.h inclusion after type declarations

Unboolify slock.c

Use explicit strcmp() instead of inlining it

Makes it a tad more readable; the previous "optimization" will be done
by the compiler anyway.
