Add appveyor conf

[rht]

• add test_go_expensive
• add appveyor pr webhook http://help.appveyor.com/discussions/questions/203-auto-run-tests-on-pull-requests @ipfs/go-ipfs-team (can only be done by someone with admin access -- not me)

[jbenet]

Oh this is great! sorry for delay-- hadn't seen it. will make an account + enable with @ipfsbot (has admin)

[jbenet]

sigh:

Repository webhooks and services
Admin access
This application will have full access to repository webhooks and services (no direct code access).

[jbenet]

Ok i added the webhook with Push and PR perms as advertised. will try re-pushing this branch

[jbenet]

Hook is firing the builds: https://ci.appveyor.com/project/ipfsbot/go-ipfs/history but they say master (probably because it will test the PR on top of master? ie apply the PR on top? not sure). This causes them to fail-- we may have to merge this first if so. wish it could build the branch directly, too (shoudnt the push build this branch, not master??)

Commit indicator still does not show. asked in appveyor/ci#527

[jbenet]

So webhook triggered. See https://ci.appveyor.com/project/ipfsbot/test/history Still missing:

• this didnt build right. build error (make)
• commit indicator. ongoing with Add to public github repo with lower perms appveyor/ci#527

(it's called "test" historically. doesn't look changeable)

[jbenet]

commit indicator shows up now. build needs to be fixed. @rht want to look into it? or someone with lots of windows experience? @Mithgol @gatesvp ?

It seems that make is not available at all and thus make install fails.

(Also your Makefile contains commands in the form env1=val1 env2=val2 someCommand and I am not sure if Windows supports such form of environment settings.)
