install Tagbar

don't dedent labels in C++

Since I hardly ever write any labels in C++, it is nice to get rid of the
annoyance of having the line dedent and reindent itself every time I write a
colon.
source local vimrc before syntax or ft plugins

This will increase performance if any bundles are declared in the local vimrc.
