More nsDialogs macros

Since some new macros have been added to nsDialogs recently, might I suggest a few more that would help in tidying up scripts a bit:

!define GWL_STYLE -16
!macro _NSD_AddStyle CONTROL STYLE
System::Call "user32::GetWindowLong(i ${CONTROL}, i ${GWL_STYLE}) i .R0"
System::Call "user32::SetWindowLong(i ${CONTROL}, i ${GWL_STYLE}, i $R0|${STYLE})"
!macroend
!define NSD_AddStyle "!insertmacro _NSD_AddStyle"

!define GWL_EXSTYLE -20
!macro _NSD_AddExStyle CONTROL EXSTYLE
System::Call "user32::GetWindowLong(i ${CONTROL}, i ${GWL_EXSTYLE}) i .R0"
System::Call "user32::SetWindowLong(i ${CONTROL}, i ${GWL_EXSTYLE}, i $R0|${EXSTYLE})"
!macroend
!define NSD_AddExStyle "!insertmacro _NSD_AddExStyle"

!macro _NSD_AddString CONTROL STRING
SendMessage ${CONTROL} ${CB_ADDSTRING} 0 "STR:${STRING}"
!macroend
!define NSD_AddString "!insertmacro _NSD_AddString"

!macro _NSD_SelectString CONTROL STRING
SendMessage ${CONTROL} ${CB_SELECTSTRING} 0 "STR:${STRING}"
!macroend
!define NSD_SelectString "!insertmacro _NSD_SelectString"

!macro _NSD_SetTextLimit CONTROL LIMIT
SendMessage ${CONTROL} ${EM_SETLIMITTEXT} ${LIMIT} 0
!macroend
!define NSD_SetTextLimit "!insertmacro _NSD_SetTextLimit"
