Composer-Setup 4.1.0

2016-03-24

• Major version pushed to v4, reflecting ShellMenus removal which requires uninstalling.
• Updated userdata.dll to handle silent uninstalls and removed the dialog cancel button, as it implied rollback functionality. File deletion can always be stopped using the dialog close icon.
• Added /PHP=path\to\php.exe and /PROXY=http_proxy url params for installation, which can additionally be saved using /SAFEINF
  and loaded with /LOADINF. For uninstall /DELETE=local will remove only local data, while /DELETE=all will remove all user data.
• Added unattended/silent install and uninstall functionality, with /SILENT, /VERYSILENT and /SUPPRESSMSGBOXES params, as per
  Inno Setup documentation.
• Changed Settings page to display a list of existing php installations. The following system drive and user profile directories are searched first: \php*, \php\php*, \bin\php*, \bin\php\php*. Then it looks for specific (xampp, wamp, PhpEd) locations.
• Simpler error handling introduced, which recognizes common PHP errors and displays all php output received.
• Added a Proxy page for the user to enter an http_proxy value, with a value pre-entered if a proxy is found in any registry Internet
  Settings. The variable is then set in the User environment (but not deleted on Uninstall). The Proxy page is also shown if http_proxy is already set or passed in as a param.
• Added a Security page for when openssl is disabled, with the option to not use it. Sets disable-tls flag for installer script
• Added installation logging, stored as Setup Log YYYY-MM-DD #nnn.txt in the users temp directory. For admin installs, the log is deleted on reboot.
• Removed Shell Menus feature to simplify the setup and further development.
