UI Nits: Add chart frame on chart

The frame on the chart wasn't shown and it looked ugly
in the add chart dialog.
Added Jon Escombe to Contributors

.. in about dialog.
Add delay after ANT reset message

Wait 500ms after sending reset message (as per ANT+ spec), before
sending any more host commands.
Change usb_bulk_read() timeout back to 125ms
Move early ANT setup after receive loop is started

Moves the early setup code so that the receive loop is already
running when these messages are transmitted. Doesn't achieve much
at this point, but can visualise the send and receive packet flow
better, and will enable the responses to these messages to be
checked in the future.
Close ANT channels before stopping session

This appears to resolve an intermittent issue with the USB2
stick not responding to reset messages when re-opened.
Postpone ANT debug log close

Don't stop debug log until the end of the receive thread (else the
traffic from the close channel messages can re-open the log file).
Whitespace cleanup (tabs to spaces)
Merge pull request #589 from dresco/ANT

ANT+ reliability fixes
About Dialog Config Tab

.. should only be shown on developer builds. When building
   releases or release candidates and GC_VERSION is being defined
   then don't add the config tab -- it is too `geeky' for the average
   end user and not at all useful for debugging.
Update QT install instructions INSTALL-LINUX

.. since Qt changed the name back to Qt 4.8 rather
than SDK 1.1.
BinRideFile: correct altitude
 handle negative value for altitude
TRIMP(100)_Points in DataFilter

.. the parenthesis caused problems so now treated as a
   special case in the lexer.
Left/Right Balance in DataFilter

.. need to make a special case as the symbol name contains
   a / character. Lexer handles it as a special case.
DBSchema increment to 44

.. was missed in April, no biggie but need to make sure
   it matches the metric definitions and comment in DBAccess.cpp
PWX support make/model for TP.com upload

.. on request from TrainingPeaks we now add the make and model
   elements to a PWX file.

Fixes #593
Add Fatigue Profiling Peak Power Durations

.. added for 2,3,8 and 90m peak power

.. user defined intervals for peak power/vam/np et al
   are still planned for v3.1

Fixes #595
LTM Show top 1 not 5 by default

.. Top 5 is a bit much, in reality defaulting to highlight
   just the top value is more useful and shouldn't lead to
   an ugly chart.
UI Nits: Fixup ScopeBar button widths

.. for different font sizes and as importantly to make the
   buttons large enough for the translated button texts -- this
   is particularly important for Deutsch.
Translation: German Analysis -> Analyse

TE Analyse is too much for such an important phrase, so
shortened it to Analyse.
