NoManualMove tag for TechnoTypes

[Metadorius]

Allows to make TechnoTypes unable to be ordered with a movement command.

[SOMETECHO]      ; TechnoType
NoManualMove=no  ; boolean

Closes #5.

On the above-linked nightly build, setting Speed=0 unit results in at least the following problems:

• Does not actually prevent issuing movement commands and the unit gets stuck like usual when you do.
• It displays no-move cursor (almost) all the time when the unit is selected, which also actually prevents manual firing, but curiously not deploying for which the correct cursor is still displayed. For a reference, deployed regular IsSimpleDeployer units actually display the default cursor unless targeting an unit and so on instead of no-move one.
