grid_export setting name misleading

[piomar123]

Hi,
The setting definition Integer("grid_export", 47509, "Grid Export Enabled", "", Kind.GRID), suggests that value 0 will block export and 1 allow it, but the actual operation is the opposite - 1 allows to apply the limit specified in grid_export_limit while 0 disables the limit and exports at the full power.
In SolarGo app, this setting is called "Power Limit".
Probably, a better name would be Grid Export Limit Enabled.
