Xenhat 0adcd693e4 Some branding and licensing work (#22)
* Fix stdafx include

* Fix basic handling of "Games" folder on Windows10 RS4 (#10)
This does the following:
- Sets the default state to hidden
- Skips the Games folder when searching

This does not:
- Hide the dead menu entry.

I do not currently know how to actively change the user preference setting to forcefully hide it.

* Add basic Visual Studio gitignore

* Add specific entries to gitignore

* Do not set default menu to Win7 on RS4 (#10)

* Rename "PC Settings" to "Settings" (#12)

* Create distinction between modern and legacy settings in search results

* Add more build artifacts to gitignore

* Add default paths for toolset and build all languages

* Fix several memsize, memtype and nullpointer issues

* create trunk branch containing all changes

* set fallback and next version to 4.3.2, set resource fallback value to allow loading in IDE

* add generated en-US.dll to gitignore

* Don't echo script contents, add disabled "git clean -dfx" to build fresh

* Initial re-branding work (#21)

* Create copy of __MakeFinal to build all languages (Use this file when releasing new versions)

* Move the registry key IvoSoft->Passionate-Coder (#21)

* Change company/mfg name IvoSoft->Passionate-Coder (#21)

* Update some leftover copyright dates (#21)

* Fix accidental copy-paste breaking MakeFinal scripts

* Fix invalid company name for Wix and change registry keys to match the new string (#21)

* Update more copyright and legal text (#21)

* Update RTF files format (Wordpad generated those) (#21)

* update license text in RTF files (#21)
We lost the blue link text in the installer page. Will have to manually re-color all the links later.
