updated year on license. aka OCD
changed Add-SshKey to prefer the HOME-EnvVar over the UserFolder ~

OpenSSH and Git uses the folder defined in the HOME Environment Variable, if declared, instead of ~\. Now also Poshgit support these.

Update prompt to use $pwd.ProviderPath

Suggested by @rpardee (#75)
Update path to TortoiseProc to reflect rename.

TortoiseGit 1.8.0 renamed TortoiseProc to TortoiseGitProc, which caused a
bug in posh-git where calling tgit would throw an exception (could not
find TortoiseProc.exe).

This commit fixes that bug, by testing whether TortoiseGitProc exists and
using that if it does.  If it does not exist, then the default
TortoiseProc is used instead.
Add .gitattributes/.gitignore
Update readme.md

Closes #81
Stop error message when id_rsa is missing

Since we set the $Env:HOME when we launch our Git Shell, we hit 
this new code path which joins that path with the .ssh\id_rsa file.
Problem is, that file doesn't exist so we get ssh-add taking a long 
time and reporting an error.

This code path should do the same thing as the old one and return 
null if the file doesn't exist.
Support for "git flow" added

Closes #76
Added file tab expansion for diff/difftool and merge/mergetool

Closes #48
Expand 'git tfs unshelve <tab>'

This has not been tested, but the pattern is tried and true.

Closes #32
Added ability to get Posh Git to write the current repository and branch to the window title
Make Window Title prefix configurable

To enable the posh-git title with no prefix:
$GitPromptSettings.EnableWindowTitle = $true

To use a custom prefix:
$GitPromptSettings.EnableWindowTitle = 'Cool: '

Also, dashes have been removed from default prefix due to Console2 bug:

add tab expansion for git cherry
Store SSH environment info in %TEMP%\.ssh

[EnvironmentVariableTarget]::User is painfully slow, because it notifies other processes of the changed value.

Closes #88
Export Get-SshPath [-File <file>]

Pretty sure GH4W has logic similar to this...might as well share.
File defaults to id_rsa.
