WIXBUG:4608 - Fix bug in mbapreq
Added localization in Portuguese to SqlExtension.
 WIXBUG:4513 - Fix condition keyword detection in modularization regex.

The regex in the modularization of conditions would incorrectly
recognize keywords that were part of property names. For example, the
property "NOTEWORTHY" would be parsed as the keyword "NOT" and the
property "EWORTHY". This fix ensures there is whitespace after keywords.
WIXBUG:4114 - PostQuitMessage in wixstdba from WM_NCDESTROY.

SHAutoComplete documentation says you need to wait for the control to be
destroyed before calling CoUninitialize. Since the window gets the
WM_DESTROY message before its child controls, the control is probably
never being destroyed. If we wait for the WM_NCDESTROY message instead,
the control will be destroyed when we call PostQuitMessage.
WIXBUG:4569 - Add SWAPRUN for CD(!) and NET back to the Burn stub.
WIXBUG:4580 - Check bit mask appropriately for Burn system variables.
WIXBUG:4600 - fix VSExtension help custom action binaries.

Updates the help custom action binaries to be proper PE-files again.
Also rename the files to have a ".dll" extension to reduce chance of
munging in the future.
