I found vanilla crafting system quite small so I expanded it. Now you can craft your favorite ammos without having their casings or breaking old ammos. You can craft explosives and energy weapons. You can even make your own new armor with increased effects!

Also all recipe names was altered to make navigation and sorting craft menu easier (check screenshots).

==============================
Thanks everyone for your help with pointing out bugs and suggestions, this mod is quite far from done so I still accept any of your notes or help.
==============================

Main point of this mod is to make previously semi-weak skills more useful, crafting more fascinating and scavenging time worthing. Now you don't need to have high repair skill in order to have brand new energy, melee weapons and armor.
Repair:now you can craft all gun ammos without breaking your ammos for details. Also you can craft weapon mods with this skill.
Explosives:you can make any explosive you want to.
Science:you can craft energy weapons and stealth boys (!) at full condition. Also you can craft energy weapon mods with this skill.
Survival:Previously food skill now allows to craft melee weapon and armor, also all hides now can be used in armorcraft.
Medicine:few fixes and some new stuff.

Perks: Vigilant Recycler and hand loader allows you to craft advanced weapon mods for energy and normal guns making these skills more useful.
Craft place: new Chemical Laboratory for scientists and medics with all related recipes. Also needed to craft basic dynamite.

=======================
Bugs/issues.
For some reason there's no icon when you select recipe of an armor to craft. Recipes for weapon and armor strangely shows wrong value for relevant items.

All new crafted helmets don't have any animation since i removed it because it displayed incorrectly on the left side of head instead of normal. I haven't found any better solution but if you happen to know please tell me.
Added: Combat helmet MK2 is still may show wrong animation, note me if it is so.
