links to smc-in-smc are not properly detected

[haraldschilly]

Make misc_page/$.fn.process_smc_links smarter by detecting if a link is going to an smc-in-smc project (maybe look for port/<number>). Right now it thinks it is on in the same SMC environment and tries to open an editor tab. In reality, it should open a new browser tab.

I think this works fine, since the default is opening a new tab … and only project specific links are detected explicitly

oh, no, the heuristic is too simple by just checking for /projects/. the point is it matters if /projects/ is rather at the start, or later (after more slashes)
