Fixed Purify complaints

[Mike Nordell]

I've checked into the problems that Purify reported about Uninitialized
Memory Read and fixed them.

af/xap/win/xap_Win32Frame.cpp from
Modify XAP_Win32Frame c'tor initializer-list

: XAP_Frame(static_cast<XAP_App *>(app)),
  m_dialogFactory(this, static_cast<XAP_App *>(app)),

to

: XAP_Frame(app),
  m_dialogFactory(this, app),
  m_iBarHeight(0),
  m_iStatusBarHeight(0)

---

text/fmt/xp/fp_Column.cpp
Add the following initializer-list to the c'tor of fp_Container

: m_iMaxHeight(0),
  m_iMaxHeightLayoutUnits(0),
  m_iHeight(0),
  m_iHeightLayoutUnits(0)

and remove the assignment of 'm_iHeight' from the body of the c'tor.

---

text/fmt/xp/fv_View.cpp
Modify the initializer-list of FV_View c'tor to

: AV_View(pApp, pParentData),
  m_bCursorIsOn(UT_FALSE)

---

wp/ap/xp/ap_StatusBar.cpp
Modify the end of the body of AP_StatusBar c'tor from

 s_iFixedHeight = 20;
}

to

 m_bufUCS[0] = 0;    // previously read before initialized
 s_iFixedHeight = 20;
}
