erlbrew can't install R15B03-1 because of file naming issue

[nalundgaard]

When installing R15B03-1:

nal-mbpr:erlbrew nal$ erlbrew install R15B03-1
Downloading Erlang R15B03-1
######################################################################## 100.0%
Tarball has correct MD5 checksum
Unpacking Erlang R15B03-1
/Users/nal/bin/erlbrew: line 104: cd: otp_src_R15B03-1: No such file or directory

It appears that this is because otp_src_R15B03-1.tar.gz expands to otp_src_R15B03 rather than the expected otp_src_R15B03-1:

nal-mbpr:erlbrew nal$ ls .build/current
erlbrew.log             otp_src_R15B03          otp_src_R15B03-1.tar.g

I worked around this by doing this from the erlbrew directory:

## clear all work folders
rm -rf .build/work.*
## in another terminal, execute 'erlbrew install R15B03-1'
## then do this immediately:
cd /build/work.*; ln -s otp_src_R15B03 otp_src_R15B03-1
cd ../..

I am not sure what the sane thing to do about this is.

I think we can solve this with a simple bash function which special cases R15B03-1 so that its build directory name matches the name in the tar ball. And if this comes up again in the future, we could reuse this "solution."

Yeah, that seems like a plan. More layers...

Or use kerl, it works really well. I've found it to work better (except for that R14 on 10.9+ issue).

@dcgibbons Should maybe hack in a way to handle patches for kerl but its just not a priority.
