Plugin for automatic TeamCity users creation based on detected VCS commits.
See http://youtrack.jetbrains.com/issue/TW-23795 for details.

Warning: Prototype, beta stage!

Prerequisites:
- non-default TeamCity authentication scheme is used (with default scheme the created user will be unable to login since noone will create a password for the user)
- VCS username is the same as login name for the user in the used TeamCity authentication scheme
- user's email has the form of <VCS username>@<domain>

Usage:
Add the following internal properties ( http://confluence.jetbrains.net/display/TCD7/Configuring+TeamCity+Server+Startup+Properties#ConfiguringTeamCityServerStartupProperties-TeamCityinternalproperties ):

{quote}
# user creation switch
vcsUsersSync.createUsers=true

# set of users to update roles for
vcsUsersSync.rolesMode=ONLY_FOR_CREATED_USERS
# other supported values are:
#vcsUsersSync.rolesMode=ALL_USERS
#vcsUsersSync.rolesMode=DISABLED

# the role to set to the matching TeamCity user
vcsUsersSync.roleId=PROJECT_DEVELOPER
#see .BuildServer/config/roles-config.xml for the list or available role ids

#email domain
vcsUsersSync.emailDomain=example.com
{quote}

Known Issues:
- with default authentication scheme the user created has empty password

ToDos:
- support adding user into a group instead of assigning role directly
- support more complex VCS_username->TeamCity_username andVCS_username->email transformation schemes
- support setting any user property (see LDAP)
