Fix, delimLen caused weird behaviour

This is useful when using commands such as tr -d '\n' to strip newlines
from output.

code cleanup.

updated readme with new statuscmd patch

delimLen didn't count in null-terminator.
On line 62 the null terminator character doesn't get copied.

Thanks to tph5595.

Change `cp`/`chmod` to `install` in Makefile

This should not affect other platforms at all.

Added first dwm style optional patch to readme

Fixes #9 - determine the size of the status buffer based on the number of blocks

Added a bit more documentation to readme.

the future will not affect csutom blocks.h files.

Fixed argument order for gcc. This most likely fixes building on debian based systems. Thanks to tph5595

This merge adds fix for issue #5 which @markcaudill fixed by having all real-time signals handled by a dummy handler if it doesn't have a refresh signal .

prevents dwmblocks from crashing because of the status string getting
longer than the underlying buffer

The install command was meant for exactly this purpose; installing a file to a location and setting its permissions. This combines the `cp` and `chmod` commands into one `install` command.

Some Makefile additions by crian

Initialize all signals from RTMIN to RTMAX with a dummy handler before
actually setting the "real" handlers.

OpenBSD.

Bug was found where certain modules caused dwm to lag horribly.
Reverting until a fix can be found.
This reverts commit 3da92ebccb.
