InstallOptionsEx

[deguix]

I modified the original version of InstallOptions to add some controls (not supported by all OS, or with others special requirements) and to make some additional changes:

- Removed NumFields from INI File "Settings" section.
- Added Animation and ProgressBar controls.
- Added ability of ComboBox and DropList controls of supporting images for each item in their list boxes.
- Added TRANSPARENT, CENTER and NOAUTOPLAY flags for Animation controls and SMOOTH and VERTICAL flags for ProgressBar controls.
- Added support of NOTIFY flag for Text, Password and ComboBox controls.

This is just beta version, it probably has some bugs and I don't know, I'm not responsible for problems it gonna make, as even it's my first touch in C++.

Included the .dll and its readme.
