[WIP] Fixing invisible stat effects (disease, pain, etc)

Before this PR stat effects from disease, pain, etc are not shown to player in any status window. (Probably due to *_cur variables not updated properly; stat effects are using related bonus variables and bonus modification functions)

<pre>
This PR is yet another push towards protected _cur and _max values, 
using getters instead (i.e. get_str, get_str_base, etc)
</pre>

Player resets for stat updates are needed for related bonus calculations, otherwise fun ensues.

Also another related typographical error fixed.

Tested with Adderall, masochist + soldering iron and traps for pain, new characters, loading saves, mutations (stat_max+ do not affect stat text coloring)

Edit: WIP: loading characters from templates crashes on "stat window"
