Finds and chooses (sets) a random research target from among all those available until presearch->researching != A_UNSET. Players may research more than one tech in this function. Possible reasons:

| void choose_tech | ( | struct research * | research, |
| Tech_type_id | tech | ||
| ) |
Called when a player chooses the tech they want to research (or when the server chooses it for them automatically).
This takes care of all side effects so the research target probably shouldn't be changed outside of this function (doing so has been the cause of several bugs).

Adds the given number of bulbs into the player's tech and (if necessary and 'check_tech' is TRUE) completes the research. If the total number of bulbs is negative due to tech upkeep, one (randomly chosen) tech may be lost. free_bulbs allows to set the bulbs free for player to invest into any tech (in multiresearch mode it happens iff the tech is not selected).
The caller is responsible for sending updated player information.
