StreamBrowserDialog rework

[fredzo]

Hi Andrew,

As discussed, here is my work on StreamBrowserDialog.
Main changes are:

• Global behaviour:
  • Properties shown in StreamBrowser are editable when possible
  • For numeric values, we can have explicit or implicit apply like in instrument/channel property dialogs
  • For explicit apply, the "apply" button is represented as small green button with "⏎" character
  • Property blocks can be displayed with a border (this is configurable)
  • A small "+" button is added at the top right corner of Property blocks to open the channel/instrument property dialog
• Oscilloscope node:
  • Added channel properties (Attenuation, Coupling, Bandwidth Limit, Invert, Offset, Range and Digital Threshold)
  • When available, digital channels are gathered in digital banks to reduce clutter
• AWG node:
  • Added shape preview
  • Added duty cycle property
• DMM node added
• For both DMM node and PSU nodes, voltage and current value can be displayed using 7 segment-like display (this is configurable)
• Session cache for instrument properties is refreshed when FlushConfigCache button is used

Editable properties:

Property blocks + channel/instrument dialog button:

Oscilloscope / AWG nodes:

DMM/PSU nodes:

@azonenberg I'm done with the requested changes:

• Updated Copyright notice
• Fixed typos
• Fixed shared pointer creation
• Added Rise and Fall time to AWG node in StreamBrowserDialog
• Removed Multimeter and FunctionGenerator dialogs
• Merged m_oscilloscopes and m_oscilloscopeStates in Session class
• Made DMM/PSU value display option a 3 option choice:
  • Console font (default)
  • 7 segment display
  • Default font
• Changed UTF8 strings to actual UTF8 symbols
• Refactored property editing methods from StreamBrowserDialog class to Dialog class + replaced "ExplcitApply" methods with new apply button design

I tried not to break anything with the ExplicitApply refactor, but could not test the following dialogs:

• RFGeneratorDialog
• LoadDialog
• DigitalOutputChannelDialog
• DigitalIOChannelDialog
