KoboMenu.cpp: cosmetic: change button "Network" to "Wifi"
KoboMenu.cpp: change poweroff to Reboot if KoboRoot.tgz exists

The Reboot feature is nice for developers who ftp the KoboRoot.tgz
file directly to the Kobo and then want to reboot.
It is not needed for normal flight.
Kobo/NetworkDialog.cpp: cosmetic: change button to "Enable Wifi"

Was "Wifi ON" which is ambiguous.
Kobo/NetworkDialog.cpp: cosmetic: change "Wifi" button to "Select network"
Event/Linux/Input: add struct Position
Event/Linux/Input: implement EV_SYN

Commit the finger position in EV_SYN, and don't allow Generate() to
access partial data.  This fixes another problem with bogus positions
on the Kobo Touch, which was not caught by the existing workaround.
Event/Linux/Input: don't use "pressed"/"released" with old position

Commit 9d028db6 implemented EV_SYN/SYN_REPORT, which means finger
movement was not committed by Generate() until this event was
received.  However BTN_TOUCH did not follow this rule, and thus the
finger position reported by these was the last known finger position,
not the new finger position (TRAC #3195, #3211).

This commit fixes the regression by splitting "pressed"/"released" to
two new attributes: "pressing"/"releasing" specifies uncommitted
changes, to be committed by EV_SYN/SYN_REPORT.
Kobo/WifiDialog.cpp: cosmetic: enlarge fonts, remove technical numbers

Make list of networks easier to read.
Kobo/WifiDialog.cpp: cosmetic: change text: "Visible" to "In range"
Kobo/WifiDialog.cpp: position  Close button in lower left corner

WifiDialog.cpp: set lower case default for wifi passwords
PlaneDetailsDialog.cpp: increase max wing area to 40 m2

For paragliders
