Plugin : Enable travis

A travis account could build nightly, to use this feature :

• Retrieve 6D5E5753F12109663BABEED53087CD3324A99FBC.gpg from any AlternC administrator (gpg key decicated to AlternCBot account)
• Retrieve GITHUB_TOKEN from any AlternC administrator or from Vault (in travis bot Notes)
• Verify .gitignore and exclude gpg file
• Login to travis as AlterncBot travis login --pro --github-token ghp_...
• Encrypt gpg file : travis encrypt-file --pro 6D5E5753F12109663BABEED53087CD3324A99FBC.gpg
• Encrypt GITHUB_TOKEN_ENV : travis encrypt GITHUB_TOKEN=ghp_...
• Encrypt GITHUB_TOKEN_VALUE : travis encrypt ghp_...

Previous 3 encrypt values must be stored in temporary content. As we have a specific travis template, we can't directly import them in our config.

• Create empty travis file touch .travis.yml
