Update `README.md` about compatibility with Windows

Fix #94
Fix some typos and errors in changelog
Bump up version to v1.3.0 for release
BUNDLED_AVR_TOOLS_DIR is now set correctly using := instead of ?=,
so that installations using only the arduino-core packages that
don't have the $(ARDUINO_DIR)/hardware/tools/avr directory can
still use the avr-g++ tools found in the $PATH (/usr/bin)

Previously BUNDLED_AVR_TOOLS_DIR was set to an empty string as
the directory doesn't exist, which meant that "ifdef BUNDLED_AVR_TOOLS_DIR..."
was set rather than skipping to "else SYSTEMPATH_AVR_TOOLS_DIR...."

No user would set BUNDLED_AVR_TOOLS_DIR so the assignment operator
:= should be used not ?=

Updated the version info/changes in various locations.

Document all the variables that can be overridden in child makefile

Huge thanks to @sej7278 for doing this

Fix #75

This target can display all variables that can be overridden
Bump up version to 1.3.1 for release
Added the arduino-mk-vars.md file to the Fedora SPECfile.

Added some notes to the SPECfile regarding overriding the paths
to the avr tools - most are in /usr/bin, but gcc/g++ are in an
architecture-dependant ccache directory

Upped version to 1.3.2 devel
Merge pull request #162 from sej7278/master

Add arduino-mk-vars.md to the RPM SPECfile.
now includes avr-libc/*.c files malloc.c and realloc.c

if bug-reporter confirms this fixes issue #163 then should be ok to merge.
Merge pull request #164 from sej7278/master

Include avr-libc/*.c files malloc.c and realloc.c
