LMMS now properly builds and runs with Qt5. Various deprecated functions
had to be replaced like QString::toAscii()/fromAscii(). Also occurences
of FALSE/TRUE have been replaced with false/true.
LmmsStyle now derives from QProxyStyle and sets a style instance as base
style (Plastique for Qt4, Fusion for Qt5).
MOC files are not included anymore but added as regular source files.
What's missing is support for embedding VST plugins into a subwindow
inside LMMS on Linux/X11 due to missing QX11EmbedContainer class in Qt5.
Build instructions can be found in INSTALL.Qt5
Minimum version requirement for Qt4 has been raised to 4.6.0 for best
API compatibility between Qt4 and Qt5.
- Stop pointlessly reloading the sample everytime the amp knob is changed
- Also draw the amplitude of the waveform correctly (used to be it was drawn as 2x too "quiet")
Samplebuffer: use qualitysettings for interpolation (currently defaults to SINC_FASTEST on playback), also: in visualize, draw both channels instead of averaging them into one graph (otherwise, samplebuffers with counter-phase content show up as flatline)
Also, some codepath optimization: add a method to SampleBuffer for setting all loop/start/endpoints at once, so we don't have to wait for mutex unlocks 4 times in a row. Then make AFP utilize this method.
Also removed all blocks similar to
```
#if QT_VERSION >= 0x040806
filedialog.setOption( QFileDialog::DontUseCustomDirectoryIcons );
#endif
```
as this now takes place in the new subclass's constructor.
