[Feature Request] 3 features request about sortie simulator

[Tan72]

1. HP setting
   Currently, HP max is 999, but now there is HP 2400 boss so please make HP max to 9999
   Also, if you copy+paste a sortie code to simulator, it cannot change HP.
   For example, if you paste
   {"f1":{"form":"13","s1":{"id":"1501","lvl":"1","hp":"999","fp":"6","tp":"15","aa":"6","ar":"5","ev":"14","asw":"25","los":"3","luk":"1","rng":"1","spd":"10","tacc":"","items":{"i1":{"id":"501"},"i2":{"id":"0"},"i3":{"id":"0"},"i4":{"id":"0"},"i5":{"id":"0"},"i6":{"id":"0"}},"morale":"49","fuel":"100","ammo":"100"}}}
   to there, but it wil still make HP 20 DD i-class, rather than HP 999 DD i-class.

2. Please make Striking force fleet (7 ships) available.

3. Please make abyssal combined fleet of night-start battle like 2017 Fall/ 2018 Winter event.
   In those events, if there is "abyssal" combined fleet on night-start battle node, it will do night battle onee (if there is BB, twice) and go to day battle.
   But in current simulator, if there is "abyssal" combined fleet on night-start battle node, 2nd fleet of abyssal will disappear and acts as same as normal night battle.
