update 0.98

- The checker now keeps a list of all tags that are allowed to be used
inside anims, weaponAnims, aug/item/crew/system/drone/weapon/ship

unrecognized / typo'd names should now show up as errors.
- name of the currently parsed file is now being displayed next to the
progress bar
- added an info about non-bomb weapons not being able to heal crew
- added an info about beam weapons not being able to apply the lockdown
effect
- fixed a bug that would cause the checker to enter an infinite loop
when the user tried to search for text in current file with no file
opened in the viewer.
- fixed a bug in search text feature that would cause the checker to
crash when the user tried to search for characters that had meaning in
regex
- added regex to the search text feature
- drone types are now considered a valid value for <choice> tags' req
