Merge pull request #16 from elbeardmorez/ac-lispdir

autoconf, fall back to default datadir install location
realgud.el: Don't try to load gub for now. It's broken and melpa doesn't know about it either.
install-from-git.sh remove old git repositories before (re-)pulling them. Use https protocol by default on git command.
configure.ac: add --with-emacs option. Check for cl-lib in emacs.
Try only emacs 24 for now. See github.com/magit for how we might use emacs 23
I said use 24.3 for emacs testing
Looks like "carton" install now uses python rather than sh
Wrong version number for emacs in .travis
Wrong path for cask in .travis
carton is now called cask? (travis yet again)
I hate travis
Fix up spelling when giving an error and regularize options given to emacs between compute-lispdir.sh and configure.ac
Add golang backtrace regexp
core.el: fix bugs in parsing gub command.
gub.el: Set default gub command to something reasonable
track-mode.el: remove some warnings by defining non-local functions
Fix gub parse args - this time, for sure! Fix tests to reduce warnings although they are still run rampant.
Reduce the number of warnings in the test directiory. One legit bug in realgud/bashdb/init.el was found/fixed though.
Add gub panic backtrace line
Mostly more declare-function statements
Remove more warnings in test programs
Reduce warnings in tests.
Reduce warnings focused mostly in directory debugger
