updated the esptool, that is, i cleaned up the command parsing. Also, it is quiet by default now, to enable some info output add -v to it's commandline argument. For more info-output use -vv, -vvv, -vvvv, ... The command -d to dump a segment into a file is deprecated noe, use -es instead. It still recognizes -d, but emits a warning then.
Also modified the Makefile for compiling apps, it now shows "FW ...." when calling esptool to create the firmware images, and also to change the -d into -ds for esptool dumping the irom0 segment.
NOTE: The Makefile uses "esptool" as name for the binary to call. Make sure you don't have a directory called "esptool" where you store the "esptool.exe" binary, it will confuse the make process and cause an error.
Attached are the updated files.
