Travis-ci fails to deploy build artifacts

[Victor Roemer]

Was apart of Issue #1

Travis-ci configuration is pretty awesome at the moment- including generation of zip archives for each platform. Currently there is a problem with the "Deploy" settings, as follows.

deploy:
  provider: releases
  api_key:
    secure: <expunged>
  file: 
    - build/release-darwin-x86_64.zip
    - build/release-darwin-x86.zip
    - build/release-linux-x86.zip
    - build/release-linux-x86_64.zip
    - build/release-mingw32-x86.zip
    - build/release-mingw32-x86_64.zip
  on:
    repo: wtfbbqhax/tremulous
    branch: blowfish-alpha-1

It looks like the CWD might be wrong at the time of the deploy:

  adding: tremded.x86_64 (deflated 54%)
  adding: tremulous.x86_64 (deflated 50%)
  adding: renderer_opengl1_x86_64.so (deflated 53%)
  adding: renderer_opengl2_x86_64.so (deflated 54%)
  adding: base/cgamex86_64.so (deflated 55%)
  adding: base/gamex86_64.so (deflated 55%)
  adding: base/uix86_64.so (deflated 57%)
  adding: base/vm/cgame.qvm (deflated 72%)
  adding: base/vm/game.qvm (deflated 72%)
  adding: base/vm/ui.qvm (deflated 73%)

Build successful.

The build logs also indicate that I need to set deploy.skip_cleanup = true:

Travis configuration is good enough for now.
