* Create .travis.yml

* Add development dependencies

* Remove enable-maintainer-mode

* Fix include path detection

Use the TCL_INCLUDE_SPEC variable from tclConfig.sh to find tcl.h

* Save after every history addition. (#2)

* Save after every history addition.

* Make autosave optional and off by default.

* Document autosave in the sample tclshrc

* Be nicer to the end user and accept anything boolean looking for autosave
