don't whine about tabs in Makefile's
tweaks to searching through IM logs

fixed `imgrep` bug where it barfed on a pattern containing spaces
created `imless` as a companion to `imgrep`
-	takes the truncated file identifier `imgrep` spits out and runs it through `less`
-	this is good for getting more context once you find the IM you were looking for
tweaks for $work setup

-	files in sandbox/bin are now moved to devtools/ in the $work repo
-	aliases in sandbox/rc are now handled by $work:bin/vagrant-sandbox-prepare
-	set up alias to cessh since I can now access that from the host
-	a better way to do `vbounce` (i.e. bounce the Vagrant sandbox)
-	some extra line added by rerunning $work:bin/install-aws-tools
fixes for some problems with my VCtools overrides & customs:

-	fixed it so `vc stage` will check for tabs for $work, but not for personal
--		this still needs more work; should rely on a per-project setting
-	`vc merge` for $work now autostashes, and farms out the heavy lifting to the relevant ceflow command
-	fixed several bugs in `vc stg-amend`:
--		can now use it on a published branch as long as the target _commit_ is not published
--		now works for filenames with spaces in them
--		untracked files in the stash no longer blow it up
--		no longer relies on `each` so is more portable
--		now has comments so I can remember how the hell it works
just a small whitespace tweak in the output of `vagrant-list`
