Create Custom Installation Folder

Added support for custom installation folder of ISL Light application and added support for changing product name.

In order to achieve this follow these steps:

1. Login to your ISL Conference Proxy administration (http://localhost:7615/conf).
2. Click Configuration -> Advanced -> Customize
3. Create or edit a customisation
4. Check the "Show expert settings" checkbox.
5. Scroll to find "ISL Light installer defaults Windows:" and use the following parameters:
   Mandatory parameters:
   AppName= (this will set the application name which can be seen in Control panel under Programs and Features)
   DefaultDirName= (this will set the installation destination folder)
   MainBinary= (this will set the name of the executable inside installation folder)
   
   Non-mandatory parameters:
   AppPublisher= (this will set the application publisher name which can be seen in Control panel under Programs and Features)
   AppPublisherURL= (this will set the application publisher URL which can be seen in Control panel under Programs and Features)
   AppSupportURL= (this will set the application support URL which can be seen in Control panel under Programs and Features)
   DefaultGroupName= (this will set the name of the application folder in Start menu)
   SkipStartMenu=(true|false) (this will allow installation of ISL Light without adding a windows Start menu icon)
   
   Example:
   AppName=TestApplicationName&AppPublisher=TestPublisher&AppPublisherURL=www.mydomain.com&AppSupportURL=&AppUpdatesURL=&DefaultDirName=%7Bpf%7D%5Ctest%5CTest%20Remote%20Control&DefaultGroupName=Test&MainBinary=Test Remote Control
6. Apart from the above mandatory parameters users must also set a name under ISL Light installation schema (example: testing -> this will enable for ISL Light to be started with a web link pointing to testing://...). Installation schema name must have at least 5 characters and maximum of 15 characters.
