Add NPPM_ADDSCNMODIFIEDFLAGS to fix regression for Plugins

Add **NPPM_ADDSCNMODIFIEDFLAGS** message for plugins which need the SCN_MODIFIED notification of other events.

BOOL NPPM_ADDSCNMODIFIEDFLAGS(0, unsigned long scnMotifiedFlags2Add)
Add needed SCN_MODIFIED flags so your plugin will recieve the notification SCN_MODIFIED of these events for your specific treatments.
By default, Notepad++ only forwards SCN_MODIFIED with the following 5 flags/events SC_MOD_DELETETEXT | SC_MOD_INSERTTEXT | SC_PERFORMED_UNDO | SC_PERFORMED_REDO | SC_MOD_CHANGEINDICATOR to plugins.
If your plugin need to process other events of SCN_MODIFIED, you should add the flags you need by sending this message to Notepad++, just after recieving NPPN_READY.
wParam: 0 (not used)
lParam[in]: scnMotifiedFlags2Add- Scintilla SCN_MODIFIED flags to add.
Return TRUE
