Fairly straight forward, the Powershell code was fundimentally just
calling Shell_NotifyIcon under the covers which we can easily do
ourself. The notification has to be tied to a window, so I simply create
a hidden one to use.
A nice improvement here is that instead of having to use the Powershell
icon we can make use of the EXE icon if one was provided. If one is not
provided then we use the default 'application' icon.
tinyfiledialogs had lots of issue surounding the quoting of the
arguments to the dialog functions. The arguments are effectively placed
verbadim into shell commands, and without any proper treatment they
would get accidentally evaluated by the shell, which is a big problem.
Additionally, any arguments containing quotes would just not work since
they would screw up the underlying shell command.
This change fixes all that for Linux. Every argument to the dialog
functions is now surrounded in single quotes, which prevents any
evaluation of the string by the shell. Additionally, because this is
standard the only chracters that need special treatment are the single
quote characters, and proper escaping for them has been added. The
result is that the dialog functions can now accept arguments that hvae
single and double quotes in them (on Linux).
Unfortunately InForm code calls this function directly via
`DECLARE LIBRARY`. For the moment we're adding it back in to keep those
programs functioning, in the future it may be removed.
I broke this by accident in 5031de2, likely by misreading the $0. What
the line was intended to do was change to the directory the script is
located in when the script starts, this allows the script to be started
from any location.
Typically this isn't necessary functionality, but for Mac OS it's
important because if you double-click the script (the typical way to run
it) it is started from the user's home directory. Due to this I also
updated the Mac OS distribution test to run the script in this way so
that it's closer to how a user will run it.
