removed FindQt4.cmake, because it is part of CMake
made adjustments in CMakeLists.txt so CMake finds QT5 (5.1.0)
adaptations for Qt 5.1.0 (Q_WS_* macros were renamed to Q_OS_*)

Fix inconsistent version in .lyx files (#7951)

LyX, lyx2lyx and tex2lyx produce now all the same version indicator consisting
only of the major and minor version. It is not decided yet whether future
development versions will add a -dev suffix, but for 2.1.0 this change fixes
the inconsistencies.
Fix JPEG format detection

Detect JPEG files using the magic number FF D8 (so-called SOI marker)
instead of the string JFIF, which does not appear in all JPEG files.
Fix pdf format conversion

When calling the default converter (convert) we pass the format on the
command line. In LyX we have various pdf, pdf2, pdf3, etc. formats all
representing PDF. We need to strip to trailing digit in the format string
otherwise the format is not understood by convert.

Fix wrong space symbols (#8729)

The main part of the fix (unicodesymbols) is from Jürgen. This commit fixes
tree problems:
- \; etc. were also used in text mode, but are math only
- all of those glyphs need to be forced with utf8
- actually, \; etc. are not the correct macros, since the encoded spaces are
  breakable, but the math spaces are all protected. The sapce symbols are not
  defined in the utf8 encodings.
Properly nest ulem commands within other font changes

This reverts the wrong fix to #8424 which caused #8733 and fixes both problems properly
Fix problem with unbalanced braces in XeTeX output (bug #8765)
Fix image pasting regression

I introduced a regression in c14b9e67 for pasting images:
If an image is on the clipboard both as PNG and HTML with just an url,
but no plain text, pasting would fail. The reason for this was that
text contents was detected (the HTML code), nd preferred, but actually
pasting it resulted in an empty string, since the HTML import could not
handle the url This error was not checked.
The solution is first to try text paste if both text and image content
is present, and then  try image paste if the text failed.
Fix Qt tools search when a Qt directory has been specified

When --with-qt-dir has been specified, programs like "moc" in the Qt
directory are unlikely to have a qualified name like moc-qt4.
Therefore, such qualified names are only considered when the base
version has not been found.
Cmake build key tests: Omit the tests and creation of xvkbd command,
if not all needed libs or programs are available.
This error is now not fatal.
Cmake build xvkbd: add xmu to the list of libraries to bind with.
This is needed (because of DSO) on ubuntu 13.04.
This is LyX 2.1.0beta1
